Kevin Easton 8a76b19ecd clone.2, execve.2: Document interaction of execve(2) with CLONE_FILES
This patch the fact that a successful execve(2) in a process that
is sharing a file descriptor table results in unsharing the table.

I discovered this through testing and verified it by source
inspection - there is a call to unshare_files() early in
do_execve_common().

Michael Kerrisk 1a212a018f execve.2: Remove unneeded ".sh" extension in interpreter script example
See https://bugzilla.kernel.org/show_bug.cgi?id=84701

As noted by C. Alex North-Keys:

1) Command name extensions considered harmful: Adding ".sh", or
any other unneeded extension, unnecessarily duplicates meta
information already present in the interpreter directive,
exposing an implementation detail that then ends up explicitly
part of other programs running this one.  Later, when such a
script is replaced with a new version in Python, C, etc., the
useless ".sh" has to be retained to avoid breaking those other
programs' calls to this one, and now has a stark antifunction
of lying about the script's content and occasionally causing
admins to run undefined experiments as root (like
"bash -x ./reallyperlscript.sh"). Such extensions, while fine
in DOS which ignores extensions explicitly, is a serious flaw
in Unix-targeted script writing.  Canonical documentation
from the Linux manual should not support such a flawed idiom -
recommending against it would be preferred.

A more extensive rant against them can be found at:
http://www.talisman.org/~erlkonig/documents/commandname-extensions-considered-harmful

2) The space after "#!" in the interpreter directive is minor -
and the kernel's fs/binfmt_script.c specifically allows for it -
but versions of unix have length limits from ~30 characters to
Linux's 127 or so (if that number's correct) so the space does
have a cost.  Most scripts I've seen lack that space, and
there's no real reason to encourage it.
