<h1> The <tt>elglob</tt> program </h1>
<p>
<tt>elglob</tt> performs globbing on a pattern, then executes
another program.
</p>
<h2> Interface </h2>
<pre>
elglob [ -v ] [ -w ] [ -s ] [ -m ] [ -e ] [ -0 ] <em>variable</em> <em>pattern</em> <em>prog...</em>
</pre>
<ul>
<li> <tt>elglob</tt> performs
<a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/glob.html">globbing</a>
on <em>pattern</em>. </li>
<li> It then performs
<a href="el_substitute.html">variable substitution</a> on
<em>prog...</em>, using <em>variable</em> as key and the result of the
globbing as value. The value is always split: it contains as many words
as they are matches for the globbing pattern. </li>
<li> <tt>elglob</tt> then execs into the modified <em>prog...</em>. </li>
</ul>
<h2> Options </h2>
<ul>
<li> <tt>-v</tt> : verbose. If there is a problem while globbing, print
a warning message on stderr. </li>
<li> <tt>-w</tt> : strict. If there is a problem while globbing, die
immediately. This is harsh - you probably don't need that option. </li>
<li> <tt>-s</tt> : sort the matches. By default, the results are
left unsorted. </li>
<li> <tt>-m</tt> : mark. Append a slash to each word that corresponds
to a directory. </li>
<li> <tt>-e</tt> : no escape. Treat backslashes in <em>pattern</em>
literally; do not allow quoting of metacharacters in <em>pattern</em> via
backslashes. <strong>Warning</strong>: the
<a href="execlineb.html">execlineb</a> launcher
uses the backslash as their own escape character - if you want a
backslash to be passed to <tt>elglob</tt>, do not forget to <em>double</em>
it. </li>
<li> <tt>-0</tt> : null globbing. By default, if <em>pattern</em>
matches nothing, it will be substituted as is (verbatim in one word). With
this option, if <em>pattern</em> matches nothing, it will be properly
substituted as zero word. </li>
</ul>
