Yup, it's true! As of the next LG issue the Linux Gazette will officially
|
|
come under the auspices of the <A HREF="http://www.ssc.com/">Linux Journal
|
|
</A>. The 'ol Linux Gazette has grown over the past year -- this is
|
|
actually its <B>First Birthday</B> this month -- and it is probably
|
|
fitting that after a year it's ready to come under the watch care of the
|
|
folks at Linux Journal. <B>Phil Hughes</B> has very graciously offered to
|
|
take over the day-to-day management of the Linux Gazette while continuing
|
|
its tradition as a free and freely available WWW publication.
|

Hi,

|
|
|
<P>
|
|
Appended is the text of an announcement that is to be sent to the various

mail lists, HowTo developers and News.
|
|
|

Hello!
|
|
|
|
<P>
|
|
Appended is the text of a forthcoming announcement about Open Linux - a
|
|
project to push Linux through XPG4-95 and UNIX-95 branding. We are gathering
|
|
opinion from the main Linux developers (such as yourself) *before* it is
|
|
released to various News Groups and mailing lists.
|
|
|
|
|
|
<P>
|
|
If you feel that you could contribute to this effort, or that what we
|
|
are doing could contribute to your work, please let us know. This is the
|
|
start of a huge collaborative effort which is widely seen as the way
|
|
forward for UNIX.
|
|
|
|
<P>
|
|
Open, GPL'ed Development.<BR>
|
|
-------------------------<BR>
|
|
This is an Open Development which will result in a Branded UNIX which
|
|
will be freely distributed on the Internet in source and binary forms.
|
|
We would welcome constructive comments about this development.
|
|
|
|
<P>
|
|
If you would like to contribute to this project, we would very much like
|
|
to hear from you. Please contact Ian Nandhra (ian@caldera.com) for more
|
|
details.
|
|
|
|
<P>
|
|
This is a real opportunity to change and re-define the UNIX industry.
|
|
|
|
<P>
|
|
Enjoy!
|
|

|
|
Caldera is looking for people who want to enhance the Linux
|
|
operating system and surrounding utilities so that they are
|
|
comformant with X/Open specifications. We feel this effort
|
|
provides a tremendous opportunity to help Linux grow beyond the
|
|
status of "Unix Clone" to full comformance with
|
|
branded UNIX. In short, Linux distributions will be able to
|
|
carry the UNIX brand. This will benefit all of us as it will
|
|
attract more ISVs and corporate customers, thus giving us all
|
|
more application choices and a broader user base of Linux
|
|
technologies.
|
|
|
|
<P>
|
|
Caldera's open development model for Caldera Open Linux:
|
|
|
|
<UL>
|
|
<LI> eliminates duplicate development paths
|
|
<LI> removes the need for multiple copies of expensive X/Open test
|
|
suites
|
|
<LI> provides GPL source that is comformant with X/Open specifications.
|
|
|
|
<P>
|
|
Note: downloaded binaries and source will not carry the X/Open
|
|
brand for UNIX 95 or XPG Base 95. People wanting to commercially
|
|
redistribute the certified and branded kernel will be able to
|
|
purchase a licence to do so from Caldera or obtain the test
|
|
suites and branding directly from the Open Group.
|
|
</UL>
|
|
|
|
<P>
|
|
Caldera respects and will protect the intellectual properties of The Open
|
|
Group, including the official X/Open branding test suites that Caldera
|
|
recently acquired from Lasermoon of Wickham, England. Caldera will provide
|
|
specs for specific technologies needed to complete the certification
|
|
and branding program, partnering with others on the Internet to enhance
|
|
Linux with POSIX and XPG4 capabilities.
|
|
|
|
<P>
|
|
Engineers and others wishing to work with Caldera in creating an X/Open
|
|
Branded Linux operating system should contact Caldera via email to Ian
|
|
Nandhra (ian@caldera.com).

|
<P>
|

For additional information about The Open Group and the X/Open brand,

via email at (rnoyes@xopen.org).
|
|
|
|
<P>
|
|
Note: On May 23, 1996, at the Linux Kongress in Berlin, Germany,
|
|
Caldera announced its plans to obtain POSIX and FIPS Certifications and
|
|
the X/Open brand for UNIX 95 and XPG4 BASE 95 for the Linux operating
|
|
system kernel. A complete news release on the topic can be viewed from
|
|
Caldera's home page at http://www.caldera.com/whatsnew/open_linux.html.
|
|
|
|
<P>
|
|
Background: Caldera is leveraging efforts originally pioneered by
|
|
Lasermoon of Wickham, England, (http://www.lasermoon.co.uk). In May, 1995,
|
|
Lasermoon gained membership in The Open Group (the leading consortium
|
|
for the advancement of open systems) and purchased the only existing
|
|
test suites for taking the Linux kernel through the X/Open branding
|
|
process. Caldera now plans to add resources to this project and manage
|
|
a cooperative effort among the Linux community, avoiding unnecessary
|
|
duplication of efforts in the certification and branding of Linux as a
|
|
full UNIX environment.

<H2>Welcome to Issue #8 of the <B>Linux Gazette !</B></H2>
|
|
|
|
<P>
|
|
We're One Year Old this month!
|
|
|
|
<P>
|
|
Yup, pretty amazing that the Linux Gazette is now a year old after starting
|
|
life as a project to learn a bit of HTML development in my spare time. Funny
|
|
how things turn out :-)
|
|
|
|
<P>
|
|
I'd like to stop at this point and offer some very heartfelt thanks to the
|
|
myriad of folks who have graciously offered help and support for the Linux
|
|
Gazette along the way. To the guys at <A HREF="http://www.tenn.com">Tennessee
|
|
CommerceNet</A> where the LG had its inception; <A HREF="http://www.redhat.com">
|
|
RedHat Software Inc.</A> who took the initial interest in the Gazette and
|
|
provided much needed WWW and FTP support; <A HREF="http://www.ssc.com">SSC and
|
|
the folks at Linux Journal</A> who offered support and encouragement as the
|
|
Linux Gazette continued to grow; to <A HREF="http://www.pht.com">Pacific
|
|
HiTech</A> for putting the Linux Gazette on its monthly <B>Mo' Linux CD</B>...
|
|
THANKS!!
|
|
|
|
<P>
|
|
Without all your help the LG wouldn't be possible.
|
|
|
|
<P>
|
|
Also, heartfelt kudos to the scores of folks who have written notes of
|
|
encouragement, suggested ideas, offered comments and criticisms, wrote
|
|
articles, provided WWW and FTP mirror sites, and took the time to drop a note
|
|
just to chat about the coolest OS on the face of the earth!
|
|
|
|
<P>
|
|
Thanks!
|
|
|
|
<P>
|
|
And to all the guys who've become regulars around the 'ol Gazette -- Ed
|
|
Cameron, Larry Ayers, Jesper Pedersen, Brian Freeze, Jens Wessling, & and
|
|
MANY MORE...
|
|
|
|
<P>
|
|
Thanks Guys!!
|
|
|
|
<P>
|
|
And finally, I want to offer a very special note of thanks to <B>Phil
|
|
Hughes</B> at the Linux Journal. Phil is one of those infectiously nice guys
|
|
that starts a casual conversation with you and after 2 hours, you're talking
|
|
and laughing like life-long buddies. He's a great guy and I'm absolutely
|
|
delighted that he and the folks at the Linux Journal have been willing to take
|
|
over the care and feeding of the Linux Gazette.
|
|
|
|
<P>
|
|
Here's a quick note from <B>Phil Hughes</B> about the upcoming transition:
|
|
|
|
<BLOCKQUOTE>
|
|
|
|
<P> Here at SSC we have always felt that the <I>Linux Gazette</I> filled
|
|
a niche that <A HREF="http://www.ssc.com/lj"> <I>Linux Journal</I></A>
|
|
could not. Being on-line it could be more timely and address topics
|
|
that would not be cost-effective in print media.
|
|
|
|
<P> When John Fisk mentioned that he might not be able to continue
|
|
publication of the Gazette because of the time committment involved, I
|
|
worked with him to make it possible for it to continue as a timely,
|
|
vendor-independent source of information on Linux.
|
|
|
|
<P> Our plans are to continue the electronic version of the Gazette (its
|
|
home is <A HREF="http://www.ssc.com/lg/"> http://www.ssc.com/lg/</A>)
|
|
plus we will offer a <I>Linux Gazette</I> section in <I>Linux
|
|
Journal</I> which will include the items we feel are of the most
|
|
interest to LJ readers.
|
|
|
|
<P> Marjorie Richardson will take over the position of Editor of the
|
|
Gazette. Her expericence in programming, working with Unix, and
|
|
technical editing for <I>Linux Journal</I> and other SSC products gives
|
|
her the needed background and experience to handle this assignment. If
|
|
you have suggestions for the Gazette or want to make a contribution to
|
|
an upcoming issue, she can be reached at
|
|
<A HREF="mailto:gazette@ssc.com"> gazette@ssc.com</A>.

You see, I've enjoyed working on the Linux Gazette like few things in life.
|
|
This has been a HUGE amount of fun and it's brought me into contact with some
|
|
of the most delightful folks in the Linux Community. It's also shown to me
|
|
the tremendous spirit of community that exists among the literally world-wide
|
|
group of Linux users. I've had mail from all over the US, Canada, Mexico,
|
|
South America, the UK, Germany, Spain, Sweden, Finland, Czechoslovakia,
|
|
Greece, Austria, Africa, the Orient, Australia, and Antarctica!
|
|
|
|
<P>
|
|
Antarctica!!
|
|
|
|
<P>
|
|
For crying out loud! There's some poor frozen guy sitting on the
|
|
coldest ice slab on the face of this planet tinkering around with
|
|
Linux!!
|
|
|
|
<P>
|
|
Seriously Way Too Cool...!!
|
|
|
|
<P>
|
|
Tell me that Bill G. gets mail from Antarctica telling him what a great OS he
|
|
has... ;-)
|
|
|
|
<P>
|
|
Anyway, it's been HUGE.
|
|
|
|
<P>
|
|
And that brings me to why I decided to turn the Gazette over to the folks at
|
|
Linux Journal.
|
|
|
|
<P>
|
|
While the LG has been a huge amount of fun this past year, it's also been a
|
|
HUGE amount of work. I figure that each issue requires in the neighborhood of
|
|
20 to 30 hours of editing, proofreading, writing, reading, and tinkering to
|
|
get ready for release -- and that DOES NOT include the piles of email that
|
|
come in and the replies that need to be handled. Nor does it include the
|
|
hours spent pouring through Usenet postings and tracking down ideas and
|
|
suggestions there.
|
|
|
|
<P>
|
|
In the last issue of the LG I put out a plea for help and I was overwhelmed by
|
|
the responce. Still, as I tried to get the LG organized and restructured it
|
|
became more and more clear that it was starting to get out of hand. Things
|
|
here in our household have been getting pretty busy as well.
|
|
|
|
<P>
|
|
So, after chatting at some length with Phil Hughes about this, I've decided to
|
|
turn the Linux Gazette over to the Linux Journal. I think that the Gazette
|
|
has demonstrated the "proof of concept" -- that a freely available
|
|
and open-to-all online publication is a great means for sharing information
|
|
and ideas. There are a number of great things that <I>could</I> be done with
|
|
this and I'm excited about the Gazette continuing on in this tradition.
|
|
|
|
<P>
|
|
Also, please know that the Linux Gazette has been, is, and will continue to be
|
|
an absolutely free publication. I can't stress this enough: I know that many
|
|
folks feel passionately about keeping Linux from <I>any</I> commercialization
|
|
whatsoever. I happen to disagree with this as it's my feeling that a free and
|
|
a commercial side can peacefully coexist and actually encourage and support
|
|
each other. That said, I've really enjoyed knowing that the Gazette has been
|
|
freely available to all and that it will continue to be so.
|
|
|
|
<P>
|
|
So, how about that for Cool Mojo! :-)
|
|
|
|
<P>
|
|
And what will happen to Your's Truly...?
|
|
|
|
<P>
|
|
What do you think... I'm gonna disappear? :-)
|
|
|
|
<P>
|
|
No, I'm pretty excited about the prospect of starting a regular column and
|
|
getting back to doing more reading, tinkering, and writing. With Phil's
|
|
permission, I'd like to continue to be very much involved with the Gazette
|
|
from the standpoint of supporting it and contributing to it -- and I'd
|
|
strongly encourage all of you to do the same. See... the reality of it is
|
|
that the folks at Linux Journal aren't going to get a red cent for doing all
|
|
of this. Now, admittedly, it's good P.R. for them -- and justifiably so since
|
|
they've been contributing to the Linux Community now for some time -- but that
|
|
doesn't change the fact that the work has to be done.
|
|
|
|
<P>
|
|
Anyway, thanks to you all!
|
|
|
|
<P>
|
|
Looking forward to another great year!

Hello,
|
|
|
|
<P>
|
|
Congratulations on your Linux Gazette, I found it to be a helluva
|
|
magazine!:) Here is an interesting little trick that you can achieve in
|
|
the ol' Linux, customising your shell prompt! Unwittingly I discovered
|
|
ages ago, you can use escape codes to produce colors et al. The article
|
|
was very recent and covered escape codes, issue 6 or 7 I think...Have
|
|
you ever wondered what directory you're in and suddenly type in rm * to
|
|
realise you were in a directory where there's precious backups etc..and
|
|
blame yourself for not pwd'ing!!!! Fear not, this little trick will tell
|
|
you what subdirectory your in each time you log in, and stays there put
|
|
until you log out!!!!!!!!!
|
|
|
|
<P>
|
|
Notation: ^[[ is accomplished by hitting Ctrl+Shift+v then Esc and the key '['!<BR>
|
|
PS1='^[[s^[[0;0H^[[K^[[0;37;44mPwd:^[[1;38;40m$(pwd)^[[u\$'<BR>
|
|
|
|
<P>
|
|
In case you're wondering, this is the ANSI escape sequences to do:<BR>
|
|
|
|
<BLOCKQUOTE>
|
|
<P>
|
|
a) save the cursor position (^[[s)<BR>
|
|
b) Goto the top of screen 0 0 (^[[0;0H) <BR>
|
|
c) Clear the line at top of screen (^[[K)<BR>
|
|
d) print the message Pwd in its colour, consult DOS manual on ANSI codes [0;37;44m)<BR>
|
|
e) print the actual directory in it's colour (^[[1;38;40m$(pwd)) $(pwd) will print the directory<BR>
|
|
f) Restore the cursor position (^[[u)<BR>
|
|
g) Y'all should know that \$ will display $ if you're not root otherwise displays #<BR>
|
|
</BLOCKQUOTE>
|
|
|
|
<P>
|
|
Hey presto, your directory is displayed on the top of the screen -
|
|
pretty nifty eh! You can stick that into your /etc/profile or
|
|
~/.profile. You can customise it to display terminal type by specifying
|
|
$(tty) etc..... Use your imagination. I came across something similar
|
|
to that in DOS, and seems to work!!! :) :)

Hi!
|
|
|
|
<P>
|
|
I have a small tip for another useful prompt modification. Even though
|
|
i know about the less-program and its ability to display binary files, i
|
|
often have the (bad) habit to just type a
|
|
<PRE>
|
|
more *
|
|
</PRE>
|
|
|
|
<P>
|
|
in the directory of a new program to get an overview of the thing. And
|
|
sometimes there is this little devil ^N who puts my console in graphics
|
|
mode.
|
|
|
|
<P>
|
|
This week, it happened again. Getting tired about echoing the necessary
|
|
^O to the terminal by hand, i've put it in my prompt:
|
|
|
|
<PRE>
|
|
export PS1=${PS1}^O
|
|
</PRE>
|
|
|
|
(as usual, ^O means control-O and is input as Ctrl-V CTRL-O in vi).
|
|
Now any graphics mode is fixed at least at the next shell-prompt.
|
|
|
|
<P>
|

Hello John,

Thank you so much for the time you spend maintaining the Gazette. I've

learned such a lot from it! Keep up your great job!

So here's my 2 cent's worth:
|
|
|
|
<P>
|
|
I was looking for a way to print Postscript files on my Deskjet using
|
|
Ghostview, since I often only need to print a few pages from large
|
|
documents. In other words, I was looking for something a little more
|
|
flexible than using ghostscript directly. What I did was to add the
|
|
following filter to /etc/printcap (filter are stored in
|

/usr/local/lib/hp510)

I use 'lp' to print text, avoiding the 'staircase effect' (A tip I
|
|
'reaped' off one of you first lg issues), while I use 'ghost' to print
|
|
Postscript files. It's also useful for printing manual pages:

man -t manpage | lpr -Pghost

Subject: vi justification<BR>
|
|
|
|
<P>
|
|
Here's a modification on a vi tip that was offered a few issues ago.
|
|
|
|
<P>
|
|
In my .exrc file, I have the following entry:
|
|
|
|
<PRE>
|
|
map ^P {!}fmt^M
|
|
</PRE>
|
|
|
|
<P>
|
|
(The "^P" and "^M" are actual control characters that I had to escape with
|
|
a <ctl>-V.)
|
|
|
|
<P>
|
|
When the cursor is anywhere within a paragraph and I hit a <ctl>-P, it
|
|
re-aligns all of the text. It's just the thing for those occasions when
|
|
you've typed in a long paragraph and then decide to delete or add several
|
|
words near the top.
|
|
|
|
<P>
|
|
I won't go into the explanation of what everything does, since that has
|
|
already been done. But rather than typing
|
|
|
|
<PRE>
|
|
:10,50! fmt
|
|
</PRE>
|
|
|
|
<P>
|
|
which requires that you know what the first and last lines of the paragraph
|
|
are, the '{' moves you to the top of the paragraph, and the trailing '}'
|
|
means to do this function up to the end of this paragraph.

OK, here's a fun little ditty that I recently came across that I've really
|
|
fallen in love with :-) It's for all of those times that you find yourself
|
|
either scooting between two directories or when you've been working in one
|
|
directory, momentarily 'cd' to another, and then need to get back to wherever
|
|
it was that you originally were at. (How about that for a run on sentance...
|
|
:-) I'm sure that I could do better with a bit of a running start and a good
|
|
tail wind...)
|
|
|
|
<P>
|
|
Anyway, I'm sure that most all of you know that the 'cd' command -- a shell
|
|
builtin function -- in BASH will automagically wisk you back to your home
|
|
directory if it's invoked without an argument. That is, if you simply type
|
|
in:
|
|
|
|
<PRE>
|
|
% cd
|
|
</PRE>
|
|
|
|
at the prompt, you'll suddenly find yourself back in your home directory from
|
|
anywhere in the system. So... this is a great little thing to remember for
|
|
all you absentminded folks that have a tendency to wander a bit. You know...
|
|
some poor freshman with a note pinned to his/her shirt: "If you find me,
|
|
please return me to my $HOME: my address is 'cd'".
|
|
|
|
<P>
|
|
Anyway, for all you BASH shell users out there, here's a bit of handiness
|
|
that goes a step beyond this and lets you find your way back to the directory
|
|
that you previously were in.
|
|
|
|
<P>
|
|
For instance, suppose that you're tooling along on some seriously cool Tcl/Tk
|
|
proggie and you realize that a bit of code from one of the demo apps might
|
|
come in handy for some little problem you've been having. No problem mon...
|
|
You just do the 'ol
|
|
<PRE>
|
|
% cd /usr/lib/tk
|
|
</PRE>
|
|
|
|
and have a look around for the code you've been looking for. OK, now you've
|
|
found it and everything's groovy (I just heard on the radio the other day,
|
|
BTW, that "groovy" is "cool" once again -- you know, no
|
|
one is using it, so it's "hip" once again, because pretty soon
|
|
everyone will be using it... I know, I know... I'm starting to ramble. Better
|
|
check the note my wife pinned to my shirt this morning... :-) anyway, where
|
|
were we...
|
|
|
|
<P>
|
|
Oh yeah, we had just stopped by the 'ol TK demo subdir to do a bit of GPL'd
|
|
plagerism and need to get back to GO. Well, there's a VERY EASY way to do
|
|
this that isn't at all intuitively obvious -- unless you've already read
|
|
through all 80 pages of the BASH manual page and then if you have -- what are
|
|
you doing hanging around here!!?
|
|
|
|
<P>
|
|
Well, to get back, you simply type in:
|
|
|
|
<PRE>
|
|
% cd ~-
|
|
</PRE>
|
|
|
|
that's a 'cd' with one of those squiggly lookin' things that lives up in the
|
|
upper left hand corner of the keyboard (a <I>tilde</I> I believe :-) and a
|
|
"dash" (or minus sign).
|
|
|
|
<P>
|
|
Do this and <I>Presto!</I> you're back in the 'ol neighborhood again!
|
|
|
|
<P>
|
|
Seriously Mucho Cool, eh?
|
|
|
|
<P>
|
|
Thought you'd like this one :-) And if you act now, you'll get at no extra
|
|
cost a set of 8 Ginzu knives... They slice... they dice... they.... (Hmmm... I
|
|
think it must be time for my medicine again :-)
|
|
|
|
<P>
|
|
Yeah, seriously, this one is pretty helpful. By now, you know all about using
|
|
the 'chvt' program that comes with the 'kbd' distribution -- use this one to
|
|
flit from virtual terminal to virtual terminal. Being able to do a bunch of
|
|
stuff at the same time is very cool and using 'chvt' lets you keep you hands
|
|
on the keyboard while you move from VT to VT. This same basic principle lets
|
|
you oscillate from one <I>directory</I> to another as you're working. Do the
|
|
'ol "cd `-" once and you're back to the directory you started in.
|
|
Do it a second time and you're back to the other directory.
|
|
|
|
<P>
|
|
Another helpful thing that you can do with this is set it up as an alias of
|
|
some kind -- use any shortcut alias you'd like. Now 'cd ~-' isn't all that
|
|
hard to write, but it's often easier to make up a quick alias. I use:
|
|
|
|
<PRE>
|
|
alias cdup='cd ~-'
|
|
</PRE>
|
|
|
|
so that I can type in 'cdup' and I'll 'cd' back up to wherever it was that I
|
|
was last at.
|
|
|
|
<P>
|
|
How about that, eh?
|
|
|
|
<P>
|
|
You know, you have to admit that the Linux Gazette can never be accused to
|
|
being <B>vaporware</B> but, truth be told, it occasionally is
|
|
<B>gaseousware</B> I mean, where else could you find an entire two pages of
|
|
verbal meanderings that boil down to, "if you type 'cd ~-' you'll change
|
|
to the directory you were last in."
|
|
|
|
<P>
|
|
Think of it as getting your money's worth...
|
|
|
|
<P>
|
|
Seriously, for those of you who might be interested, this is an example of
|
|
<B>TILDE EXPANSION</B> which is a feature of the BASH shell. Check the manual
|
|
page for more info.
|
|
|
|
<P>
|
|
Enjoy! :-)

<H3><IMG ALIGN=BOTTOM SRC="./gx/opus.gif">HTML Clean up Macro</H3>
|
|
|
|
<P>
|
|
OK, here's another fun little item that can save you HTML authors out there a
|
|
bit of time. I've been doing a bit of writing over the past year and
|
|
repeatedly come back to <B>VIM</B> as my hands-down favorite editor for simply
|
|
getting things done. It's one of those editors which, if you keep you fingers
|
|
on the keyboard and not have to peek all the time or feel compelled to push a
|
|
mouse or other small rodent around to get work done, let's you get things done
|
|
VERY quickly. Now, you can say the same thing about <B>Emacs</B> I suspect,
|
|
but since I'm still using 'ol VI, you're stuck having to listen to me talk
|
|
about this for the moment :-)
|
|
|
|
<P>
|
|
Anyway, one of the cool things about VI is the ":so" command which
|
|
basically let's you create a series of command-mode commands which you save to
|
|
a text file, and then you can simply have VI "source" this in order
|
|
to run the commands.
|
|
|
|
<P>
|
|
Since there's nothing like a good example to clear things up, let's see how to
|
|
use this with doing a bit of pre-formatting for HTML.
|
|
|
|
<P>
|
|
As you all know, there are several characters which are not
|
|
"allowed" to be directly included in the text portion of an HTML
|
|
document -- these are the "reserved" characters and they include:
|
|
|
|
<UL>
|
|
<LI>the ampersand character: &
|
|
<LI>the less-than character: <
|
|
<LI>the greater-than character: >
|
|
<LI>the double-quote character: "
|
|
</UL>
|
|
|
|
When a browser parses the HTML document these characters are used to convey
|
|
formatting or other information and so cannot be directly input.
|
|
|
|
<P>
|
|
The problem comes in when you want to include text in an HTML document.
|
|
Specifically, I include a lot of email in the 'ol LG. Problem is, that much
|
|
of it contains so-called "reserved characters" -- those characters
|
|
enumerated above that should not be directly entered into the text. In the
|
|
past I've manually searched through each letter trying to ferret these out
|
|
but, as with most Linux things, there's a MUCH easier and more efficient way
|
|
to do this.
|
|
|
|
<P>
|
|
As your Uncle Louigi says, "Use your head, not your back..."
|
|
|
|
<P>
|
|
So, the first thing to note is that the first step in the email->HTML
|
|
conversion is converting these characters to either a "Character
|
|
Reference" or an "Entity Reference" (you know -- you have to
|
|
use &quot; for the (") double-quote character). You can easily do
|
|
this using something like:
|
|
|
|
<PRE>
|
|
:%s/\&/\&amp;/g
|
|
</PRE>
|
|
|
|
This particular command does a global substitution for the current file by
|
|
converting every instance of "&" to "&amp;". Do
|
|
this for the other three reserved characters and you'll be on your way to
|
|
dropping your email (or any other text document for that matter) into your
|
|
HTML docs.
|
|
|
|
<P>
|
|
Now, you could obviously just enter these commands in by hand each time you
|
|
want to do this, but hey, this is Linux and being lazy is OK -- as long as
|
|
you're <I>smart</I> about it :-)
|
|
|
|
<P>
|
|
So, instead of typing in a set of commands to convert these characters to
|
|
their Entity Reference format, we'll just set up a macro file which can be
|
|
sourced for any text file. Using something like:
|
|
|
|
<PRE>
|
|
%s/\&/\&amp;/g
|
|
%s/</\&lt;/g
|
|
%s/>/\&gt;/g
|
|
%s/\"/\&quot;/g
|
|
</PRE>
|
|
|
|
will let you convert these automagically. So, how do you do this? Easy:
|
|
|
|
<OL>
|
|
<LI>Create a plain text file and copy the above lines to it
|
|
<LI>Save the file with some catchy little title such as "htmlconv"
|
|
<LI>Load up some test document that you want to experiment on
|
|
<LI>Now, just issue the command ";so /path/to/file/htmlconv"
|
|
</OL>
|
|
|
|
and <I>Presto!!</I> VI will grind away for a moment and all of the changes
|
|
will be made for you.
|
|
|
|
<P>

Sourcing a macro file is one way to improve the speed and efficiency of doing
|
|
things under VI(M) -- especially if you find yourself doing tasks that
|
|
required frequent repetition. One small suggestion is to put these macros in
|
|
their own directory off your HOME directory so that they are easily accessible
|
|
from anywhere in the directory tree. To specify such a macro you could enter:
|
|
|
|
<PRE>
|
|
:so ~/macros/htmlconv
|
|
</PRE>
|
|
|
|
and the tilde (~) would be automagically expanded out to point to your home
|
|
directory.
|
|
|
|
<P>
|
|
Anyway, this is one of those "tip of the iceburg" types of things
|
|
because there is a HUGE amount of mischief you can get into using macros :-)
|
|
|
|
<P>
|
|
Have fun!

<H3><IMG ALIGN=BOTTOM SRC="./gx/opus.gif">Getting Rid of ^M's</H3>
|
|
|
|
<P>
|
|
OK, I *promise* to keep this one nice and short.
|
|
|
|
<P>
|
|
If you use Linux long enough you'll eventually find yourself with an annoying
|
|
case of "^M" infestation in some file you've just created or are
|
|
working on. For my Comp Sci classes this past year I was required to do a
|
|
"script" output for each of my progamming projects: start the
|
|
'script' program, 'cat' the source file, compile it, and then run it. This
|
|
created a log file which had to be turned in. One of the most annoying things
|
|
about doing this was, at least on my Linux box, that it was replete with
|
|
"^M" at the end of each line. You'll also find that occasional DOS
|
|
files will have these scattered all throughout them as well.
|
|
|
|
<P>
|
|
So, how do you get rid of them without resorting to an exterminator...?!
|
|
|
|
<P>
|
|
Glad you asked :-)
|
|
|
|
<P>
|
|
A while ago, there was a thread in one of the comp.os.linux.xxxxx gruops about
|
|
this very subject. I'd discovered how to get rid of the ^M's easily from
|
|
within VIM but a number of other of suggestions were made as well and so I'll
|
|
present these. I apologize to their original authors. I wrote the ideas down
|
|
but neglected to write down who offered them. If you recognize any of these
|
|
as "your's" then please drop me a note and I'll be glad to give
|
|
credit where credit is due.
|
|
|
|
<P>
|
|
Anyway, here's how:
|
|
|
|
<DL>
|
|
<DT>From within VIM use the command <B>:%s/^V-RETURN//g</B>
|
|
<DD>You'll need to get out of edit mode to do this one (hit ESC). Enter
|
|
a colon, percent sign, the letter 's', and a forward slash. Now, you'll
|
|
need to use the Ctrl-V key combination to enter a literal key: hit the
|
|
control and 'v' key together and then hit the ENTER (or RETURN) button
|
|
which should display a '^M'. Now, hit two more forward slashes and the
|
|
letter 'g'. Hit ENTER and you're done!
|
|
|
|
<P>
|
|
What this does is a global substitution through the entire file. Each
|
|
occurrence of the ^M (which is a "carriage return" -- remember
|
|
that UNIX uses only the line feed (LF) character to start a new line
|
|
whereas DOS uses the carriage return + line feed characters (CR + LF) to
|
|
start a new line) is substituted by, well, nothing. So this effectively
|
|
erases each occurrence of the ^M.
|
|
<P>
|
|
|
|
<DT>At the command line use <B>sed</B>
|
|
<DD>You can use 'sed' (the Stream Editor) to trim out those unwanted ^M's
|
|
in a couple different ways:
|
|
|
|
<PRE>
|
|
% sed 's/^M//' < ORIG.FILE > new.file
|
|
-OR-
|
|
% sed 's/.$//' < ORIG.FILE > new.file
|
|
</PRE>
|
|
|
|
Just a couple points here...
|
|
|
|
<P>
|
|
For the first example the "orig.file" is the file that you wish
|
|
to remove the ^M's from and the "new.file" is what you want to
|
|
call the edited file. <B>Don't use the same filename!</B> If you do,
|
|
you'll be sorry as the contents of your original file will be deleted by
|
|
doing this. <I>Caveat Emptor!</I>
|
|
|
|
<P>
|
|
Also, the "^M" is the same control-v + RETURN combination
|
|
mentioned above. The standard UNIX editors VI and Emacs both let you
|
|
insert characters literally (this let's you insert characters such as the
|
|
Escape key that are normally non-printing keys). The Bourne shells tend
|
|
to use VI keymappings and the C-shells tend to use Emacs binding. Thus,
|
|
if you're using BASH you'll use control-v to insert a literal character at
|
|
the command line and then hit ENTER (or RETURN) to insert a literal
|
|
carriage return character.
|
|
|
|
<P>
|
|
The second example doesn't use any of this type of literal character stuff
|
|
-- just type it in as you see it and it'll work!
|
|
<P>
|
|
|
|
<DT>Pipe the file through <B>tr</B>
|
|
<DD>You can use the 'tr' (translate) utility to accomplish the same basic
|
|
thing by doing something like:
|
|
|
|
<PRE>
|
|
cat orig.file | tr -d \\r > new.file
|
|
</PRE>
|
|
|
|
Again, there's no tricky literal character input here; you just type it in
|
|
as listed above. Do note, however, that you <I>pipe</I> the output of the
|
|
'cat' operation to 'tr' and then <I>redirect</I> the output from 'tr' to
|
|
the new file you wish to create. And don't forget to use a different name
|
|
for the new file!
|
|
<P>
|
|
</DL>
|
|
|
|
<P>
|
|
Well, hopefully, that should get you going!
|
|
|
|
<P>
|
|
Enjoy.

Hello!
|
|
|
|
<P>
|
|
I am writing to you today in response to your request for help with the
|
|
Linux Gazette.
|
|
|
|
<P>
|
|
I feel that if there is one area where Linux proves it's strength it is when
|
|
connecting a PC to a TCP/IP network. Seeing as more an more people get
|
|
access to PPP dialup accounts, I think it would be nice with a column about
|
|
all the things you could do using such a connection. The thing is: If you
|
|
got a PPP connection to the Internet, you got your own IP address, you can
|
|
actually do anything anyone else does.
|
|
|
|
<P>
|
|
I have a Linux machine connected to our company LAN. On it's responsible for
|
|
retrieving our eMail, it runs a Web server and FTP server. It runs a news
|
|
server for our LAN, downloading a selected set of newsgroups whenever it
|
|
goes online. It's got sendmail configured (like you described in a previous
|
|
issue of LG) to queue remote mail, while delivering local mail immediately.
|
|
It also function as our Internet gateway, by using something called
|
|
IPMasquerade. This enables all the machines on our LAN to access the
|
|
Internet through this machine, and without the cooperation of our ISP (saves
|
|
us equivalent of hundreds, if not thousands of dollars).
|
|
|
|
<P>
|
|
Such a column would start with the basics of setting up PPP, sendmail,
|
|
popclient and things like that. Then we could move to other interesting
|
|
things like setting up a news server, a Web server and a FTP server.
|
|
Obviously some security stuff would also be needed.
|
|
|
|
<P>
|
|
If you thing a column like this would be a good idea, please feel free to
|
|
get back to me.
|
|
|
|
<P>
|
|
It's not like I don't have enough to do, but I spend quite a lot of time
|
|
with Linux already, and a project like this would be a great way for me to
|
|
document some of the thing I do. I will start setting up a similar system
|
|
for a client shortly, so I could probably take a lot of this stuff from my
|
|
notes on that system.
|
|
|
|
<P>
|
|
I have the ability to produce on a regular basis (once a month, wasn't it?
|
|
:), and the time to receive and READ any eMail it my writing generates. I'm
|
|
also quite capable of writing HTML.
|
|
|
|
<P>
|
|
Anyway, you probably get a lot of eMail, so I think it's time for me to shut
|
|
up, and await your reply.

The <B>Java Development Kit (JDK)</B>, ported to Linux by the kind folks
|
|
at <B>Blackdown</B>, allows Linux users to compile java source code to produce java class
|
|
files. However, the JDK requires a <B>Linux ELF</B> system and will
|
|
not work on an <B>a.out</B> system. The Netscape Navigator (version 2.0
|
|
and higher) contains a java compiler which can be used to compile
|
|
java source code on <I>a.out</I> and <I>ELF</I> Linux systems.

<H3>USAGE</H3>
|
|
To use the <B>javacc</B> script, invoke it as follows :-
|
|
<BR><P>
|
|
<CENTER><I>
|
|
javacc java-source-file.java
|
|
</I></CENTER>
|
|
<BR><P>
|
|
<B>USAGE NOTES:</B>
|
|
<OL>
|
|
<LI>
|
|
The script checks to see if a source file parameter has been entered. If
|
|
no parameter is specified, the script comes up with a usage message.
|
|
<BR>
|
|
<LI>
|
|
If multiple command line parameters are entered, the script only uses
|
|
the first parameter as the java source code file name and ignores all
|
|
other parameters
|
|
</OL>
|
|
<BR><P>
|
|
If the java compilation is successful, a java bytecode file, with
|
|
the extension <B>.class</B> is created. This is the java applet.

Well, once again I owe a HUGE debt of thanks to <B>Larry Ayers</B> for his
|
|
absolutely wonderful and prolific reviews of a LOT of great software. His
|
|
first document on <B>New Releases and Revisions</B> includes reviews of:

<LI>An Nedit that works
|
|
<LI>ELF-based Andrew User Interface System (AUIS)

|
|
<LI>A Couple New Process Meters
|
|
</UL>
|
|
|
|
<P>
|
|
His next review takes a look at an impressive <B>Tcl/Tk</B> based desktop
|
|
management utility: <B>TkDesk</B>. And finally, there's a review of the
|
|
<B>VM- and html-help-modes</B> available for Emacs.
|
|
|
|
<P>
|
|
These are GREAT reviews. There are some very nice descriptions and
|
|
screen shots for several programs. Drop Larry a note (and for that
|
|
matter, drop <I>any and all</I> of the contributing authors a note!) of
|
|
thanks for this!

I've said this before but it certainly bears repeating: "99% of all Linux
|
|
users are their own system administrators and <I>every</I> system
|
|
administrator needs to know how to shell program!"
|
|
|
|
<P>
|
|
In view of this, I'm very pleased to include this great shell programming
|
|
article by <B>Geoff Taylor</B>. In this article he'll take you through the
|
|
writing of a couple pretty useful shell programs: <B>px</B> and
|
|
<B>search</B>.
|
|
|
|
<P>
|

I REALLY appreciate Geoff's contribution. There's a HUGE amount of fun and

|
useful things that can be done with a little bit of shell know-how and I'd
|
|
welcome any other such submissions!

One of the things that I've been truly amazed by over and over again is the
|
|
tremendous sense of generosity and <I>esprit de corps</I> that exists within
|
|
the Linux Community. A number of you have written and sent in articles for
|
|
the Linux Gazette. While I appreciate articles that come
|
|
"pre-tagged" for HTML, I also appreciate anyone's willingness to
|
|
write and share their ideas.
|
|
|
|
<P>
|
|
This collection of articles are those that I tagged up -- because time has
|
|
been such an exasperating problem recently I took the liberty of collecting
|
|
these altogether and including them in a single file (I'm afraid it isn't
|
|
quite as fancy as those many of you have sent in).
|
|
|
|
<P>
|
|
These are some <I>excellent</I> articles and I'd encourage you all to at least
|
|
skim though these as they touch on a number of very practical subjects. So
|
|
that you have an idea about what is included, here's the TOC so that you can
|
|
jump right to an article that sounds interesting to you:

Well, I have to admit that I've been a bit of a "stick-in-the-mud"
|
|
until recently when comes to kernels. I'd been stubbornly running kernel
|
|
1.2.13 for months while the rest of you "Bleeding Edge" kinda folks
|
|
gradually ascended higher and higher into the 1.3.x kernels :-)
|
|
|
|
<P>
|
|
Since I use Linux for my Internet connection and do all of my HTML
|
|
development under it I really wanted stability. However, once the 2.0
|
|
kernel came out and <B>Michael K. Johnson's</B> article in the <B>Linux
|
|
Journal</B> provided a concise summary of the improvements from the
|
|
1.2.x -> 2.0.x kernels, I decided to take the plunge.
|
|
|
|
<P>
|
|
Well, I did it and I'm pretty happy about it! :-)
|
|
|
|
<P>
|
|
It's not as bad as it sounds and it really is worth the effort. What I'd like
|
|
to do is share with you about how this upgrade went for <I>me</I>. Your
|
|
experiences will probably be different depending on the hardware that you're
|
|
running, which distribution you're using, and so forth.
|
|
|
|
<P>
|
|
Still, I really believe that it's worth the effort!
|
|
|
|
<P>
|
|
I'd be delighted to hear from any of you who've done that same thing. Drop me
|
|
a note and let me know how things went for you!

Hope you enjoy.

I recently submitted an article to the <A HREF="http://www.ssc.com">Linux

Journal</A> for the <B>Novice to Novice</B> column. I really appreciate the

generosity of the folks at the LJ and, with their permission, have included

the draft of this article here.
|

<P>
|

This particular article contains mostly stuff that I or someone else has

written about before in the LG, but for those of you who may be visiting and

who haven't seen those articles, here's a bit of information on keyboard
|

mapping, switching virtual terminals (VT's), and other fun stuff.

Well, I think we're almost ready to go. It's funny... I've mentioned this
|
|
before but I really enjoy writing this section of the LG. I purposely wait to
|
|
write this last and, kind of like coming home after a busy day, it's nice to
|
|
kick back and just chat.
|
|
|
|
<P>
|
|
As I mentioned before, I can't tell you how pleased, relieved, and excited I
|
|
am about turning the LG over to Linux Journal. I think that this will be a
|
|
Very Good Thing primarily because it deals with one of the things that
|
|
frustrated me more than anything else -- not being able to get the Gazette out
|
|
on a regular and timely fashion. I am really excited about the Gazette being
|
|
published in a more predictable fashion as I know that many of you wrote about
|
|
this.
|
|
|
|
<P>
|
|
Also, since I haven't had much time to do any serious 'Net cruisin' recently
|
|
let me share with you, if you don't mind, a project that I started tinkering
|
|
around with a while ago. One of the things that I was hoping to do over the
|
|
summer was learn a bit of <B>Tcl/Tk</B> programming. While I haven't had
|
|
nearly the amount of free time to do this as I'd hoped, I still found a bit of
|
|
time earlier this summer to play around with an X Window interface for pppd.
|
|
|
|
<P>
|
|
I have to admit, Tcl/Tk is just too much fun! Now, I'm not sure that I'd want
|
|
to be building <B>Lotus Smart Suite or Microsoft Office</B> in Tcl/Tk, but for
|
|
small project and programs this is just too much fun. What I wanted to do was
|
|
to create a front end for pppd that I could use either as 'root' or as a user.
|
|
I also wanted it to have a few little "extras" such as a timer, line
|
|
selection, and logging facility. Well, it turned into a LOT of fun and after
|
|
a bit of tinkering and pouring over <B>John Ousterhout's and Brent Welch's</B>
|
|
books on Tcl/Tk programming, I finally got an admittedly <I>alpha</I> version
|
|
up and running.
|
|
|
|
<P>
|
|
For the curious, here's a miniature screen dump:

Well, if you're interested, here's a <A HREF="./ppptk.html">full screen view
|
|
</A> of the program together with a brief description of what it does.
|
|
|
|
<P>
|
|
Now, I admit that I'm no serious Tcl/Tk programmer, but I've been REALLY
|
|
impressed with how well this little program works and how easy it's been to
