<strong>Synopsis</strong>
|
||
|
|
|
||
|
|
<p><strong>alias [ -p ]</strong> [ <em>name</em> [ <em>=value</em>
|
||
|
|
] ... ]</p>

|
|
|
||
|
|
<p><strong>Description</strong></p>
|
||
|
|
|
||
|
|
<p>The <strong>alias</strong> utility defines an alias <em>
|
||
|
|
name</em> that has the specified <em>value</em>. If only
|
||
|
|
<em>name</em> is specified, <strong>qsh</strong> displays the name and
|
||
|
|
value of the alias.</p>
|
||
|
|
|
||
|
|
<p>When no arguments are specified, <strong>qsh</strong> displays a
|
||
|
|
list of all the aliases and their values.</p>
|
||
|
|
|
||
|
|
<p><strong>qsh</strong> defines these default aliases:
|
||
|
|
<ul>
|
||
|
|
<li>float='declare -E'</li>
|
||
|
|
|
||
|
|
<li>functions='declare -f'</li>
|
||
|
|
|
||
|
|
<li>integer='declare -i'</li>
|
||
|
|
</ul>
|
||
|
|
</p>

<dl>
|
||
|
|
<dt><strong>-p</strong></dt>
|
||
|
|
|
||
|
|
<dd>Precede each line of the output with the word "alias " so it is

|
||
|
|
<p>Each <em>name</em> specifies an alias in the current
|
||
|
|
environment. If a <em>value</em> is also specified, then the value
|
||
|
|
of the alias is updated.</p>
|
||
|

|
|
<p><strong>Exit Status</strong></p>

|
|
<li>0 when successful.</li>
|
||
|
|
|

<li>>0 when unsuccessful. The value is the number of <em>
|
||
|
|
names</em> that are not aliases.</li>
