<h2>nohup - Run utility without hangups</h2>

<strong>Synopsis</strong>
|
||
|
|
|
||
|
|
|
||
|
|
<p>
|
||
|
|
<strong>nohup [ -C</strong> <em>ccsid</em> <strong>]</strong> <em>utility</em> <strong>[</strong> <em>argument</em> ... <strong>]</strong>
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p><strong>Description</strong></p>
|
||
|
|
|
||
|
|
<p>The <strong>nohup</strong> utility runs the specified <em>utility</em> with
|
||
|
|
the specified <em>arguments</em>. When <em>utility</em> is invoked the SIGHUP signal is set
|
||
|
|
to be ignored. You can use <strong>nohup</strong> to allow <em>utility</em> to run
|
||
|
|
even after ending the <a href="commands.htm">Qshell session</a>.</p>
|
||
|
|
|
||
|
|
<p>If standard output is a terminal, all output written by <em>utility</em> to its
|
||
|
|
standard output is appended to the file nohup.out in the current directory. If the file
|
||
|
|
cannot be created or opened for appending, all output is appended to the file $HOME/nohup.out.
|
||
|
|
If neither file can be created or opened, <em>utility</em> is not run. The default permission
|
||
|
|
for the nohup.out file allows only the owner to read and write the file.</p>
|
||
|
|
|
||
|
|
<p>If standard error is a terminal, all output written by <em>utility</em> to its
|
||
|
|
standard error is redirected to the same descriptor as standard output.</p>

|
<dd>The nohup.out file is created with the specified <em>ccsid</em> and all data written to the file
|
||
|
|
is converted from the CCSID of the job to the specified <em>ccsid</em>. This option
