|

patterns used, e.g., by Unix utilities such as
|

<span class="citerefentry"><span class="refentrytitle">grep</span>(1)</span>,

<span class="citerefentry"><span class="refentrytitle">sed</span>(1)</span>,
|

and
|

<span class="citerefentry"><span class="refentrytitle">awk</span>(1)</span>.
|
||
These use conventions similar to but more elaborate than those described
|
||
under <a href="../G/glob.html"><i class="glossterm">glob</i></a>. For purposes of this lexicon, it is
|
||
sufficient to note that regexps also allow complemented character sets
|
||
using <tt class="literal">^</tt>; thus, one can specify ‘any non-alphabetic
|
||
character’ with <b class="command">[^A-Za-z]</b>. </p></dd><dd><p> 2. Name of a well-known PD regexp-handling package in portable C,
