<p><strong>Synopsis</strong></p>

<strong>attr [ -hp ]</strong> <em>file</em> <strong>[</strong> <em>attribute</em> <strong>[</strong> <em>=value</em> <strong>]</strong> ... <strong>]</strong>

|
<p><strong>Description</strong></p>
|
||
|
|
|
||
|
|
<p>The <strong>attr</strong> utility gets or sets attributes for the object specified by <em>file</em>.
|
||
|
|
When no <em>attributes</em> are specified, <strong>attr</strong> displays all of the attributes
|
||
|
|
for the object in a re-entrable format to standard output. When an <em>attribute</em> is specified,
|
||
|
|
<strong>attr</strong> displays the value of the attribute to standard output.
|
||
|
|
When an <em>attribute</em> and <em>value</em> are specified, <strong>attr</strong> sets
|
||
|
|
the attribute to the value. Note that all attributes can be displayed, but
|
||
|
|
only some attributes can be set.</p>
|
||
|
|
|
||
|
|
<p>
|
||
|
|
For date and time attributes, the value displayed by default is formatted with
|
||
|
|
the asctime() function. If the LC_TIME environment variable is set, the value
|
||
|
|
displayed is formatted with the format specified by the d_t_fmt keyword in the
|
||
|
|
LC_TIME category of the specified locale.</p>
|
||
|
|
|
||
|
|
<p>See the <a href="../apis/qgetattr.htm">Qp0lGetAttr()</a> API for detailed
|
||
|
|
information about the attributes and their values.</p>
