|

<a href="../F/flatten.html"><i class="glossterm">flatten</i></a>ed representation of a set of one or more
|
||
files, with the unique property that it can be unflattened (the original
|
||
files restored) by feeding it through a standard Unix shell; thus, a
|
||
sharchive can be distributed to anyone running Unix, and no special
|
||
unpacking software is required. Sharchives are also intriguing in that
|
||
they are typically created by shell scripts; the script that produces
|
||
sharchives is thus a script which produces self-unpacking scripts, which
|
||
may themselves contain scripts. Sharchives are also commonly referred to as
|
||
‘shar files’ after the name of the most common program for
|
||
generating them.</p><p>The downsides of sharchives are that they
|
||
are an ideal venue for <a href="../T/Trojan-horse.html"><i class="glossterm">Trojan horse</i></a> attacks and
|
||
that, for recipients not running Unix, no simple un-sharchiving program is
|
||
possible; sharchives can and do make use of arbitrarily-powerful shell
|
||
features. For these reasons, this technique has largely fallen out
|
||
of use since the mid-1990s. </p></dd><div class="navfooter"><hr/><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="shar-file.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="../S.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="Share-and-enjoy-.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">shar file </td><td width="20%" align="center"><a accesskey="h" href="../index.html">Home</a></td><td width="40%" align="right" valign="top"> Share and enjoy!</td></tr></table></div></body></html>
