<p><strong>Description</strong></p>
|
||
|
|
|
||
|
|
<p>The <strong>hash</strong> utility adds <em>utility</em> to the
|
||
|
|
list of remembered utility locations or removes all remembered
|
||
|
|
utilities from the list. By default, <strong>hash</strong> uses a
|
||
|
|
path search to find <em>utility</em>.</p>
|
||
|
|
|
||
|
|
<p>When no arguments are specified, <strong>hash</strong> reports
|
||
|
|
the contents of the list. An entry that has not been looked at
|
||
|
|
since the last <a href="cd.htm">cd</a> command is marked with an
|
||
|
|
asterisk; it is possible for the entry to be invalid.</p>
