|

<H2><A NAME="ss4.2">4.2 Easy to set up, fairly easy to use, no need for root privileges:</A>

<A HREF="mailto:leonard@sct1.is.belgacom.be">Leonard Jean-Marc</A> for the tip. Thanks also to

<P>In your .bashrc, you can put in a line like this:

|
<BLOCKQUOTE><CODE>
|
|
<PRE>
|
|
alias btar='tar --use-compress-program /usr/local/bin/bzip2 '
|
|
</PRE>

</CODE></BLOCKQUOTE>
|
|
<P>
|
|
<P>In your .tcshrc, or .cshrc, the analogous line looks like this:
|
|
<BLOCKQUOTE><CODE>
|
|
<PRE>
|
|
alias btar 'tar --use-compress-program /usr/local/bin/bzip2'
|
|
</PRE>
|
|
</CODE></BLOCKQUOTE>
|
|
<P>
|
|
<H2><A NAME="ss4.3">4.3 Also easy to use, but needs root access.</A>
|
|
</H2>
|

<P>Update your tar to GNU's newest version, which is currently 1.13.10.
