<strong>Synopsis</strong>

|
|

|
|
<p><strong>getconf</strong> [ <em>name</em> [ <em>pathname</em> ]

|
<p><strong>Description</strong></p>
|
||
|
|
|
||
|
|
<p>The <strong>getconf</strong> utility displays the POSIX
|
||
|
|
configuration variables. If you specify <em>name</em>, <strong>
|
||
|
|
getconf</strong> displays the value of the configuration variable on
|
||
|
|
standard output. When the configuration variable depends on a path
|
||
|
|
name you must specify <em>pathname</em>.</p>
|
||
|
|
|
||
|
|
<p>When no arguments are specified, <strong>getconf</strong> displays a
|
||
|
|
list of all the configuration variables and their values. For those
|
||
|
|
configuration variables that depend on a path name, <strong>
|
||
|
|
getconf</strong> uses /.</p>
