<h2>Using a Qshell interactive session</h2>
|
||
|
|
|
||
|
|
<p>The Start QSH (STRQSH) command, also known as QSH, is a CL
|
||
|
|
(control language) command that either starts a Qshell interactive
|
||
|
|
session or runs a Qshell command.</p>
|
||
|
|
|
||
|
|
<p>If running in an interactive job with no parameters, STRQSH
|
||
|
|
starts an interactive Qshell session. If a Qshell session is not
|
||
|
|
already active in the job, then the following events occur:</p>
|
||
|
|
|
||
|
|
<ol>
|
||
|
|
<li>A new Qshell session is started and a terminal window is
|
||
|
|
displayed.</li>
|
||
|
|
|
||
|
|
<li><strong>qsh</strong> runs the commands from the file
|
||
|
|
/etc/profile if it exists.</li>
|
||
|
|
|
||
|
|
<li><strong>qsh</strong> runs the commands from the file .profile
|
||
|
|
in the user's home directory if it exists.</li>
|
||
|
|
|
||
|
|
<li><strong>qsh</strong> runs the commands from the file specified
|
||
|
|
by the expansion of the <strong>ENV</strong> variable if it
|
||
|
|
exists.</li>
|
||
|
|
</ol>
|
||
|
|
|
||
|
|
<p>If a Qshell session is already active in an interactive job, you
|
||
|
|
are reconnected to the existing session.</p>
|
||
|
|
|
||
|
|
<p>From the terminal window, you can enter Qshell commands and view
|
||
|
|
output from the commands. The terminal window has two parts:</p>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>an input line for entering commands</li>
|
||
|
|
|
||
|
|
<li>an output area that contains an echo of the commands you
|
||
|
|
entered and any output generated by the commands</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<p>You can use these function keys:</p>
