<h2>Customizing your environment</h2>
|
|
|
|
<p>You can customize your Qshell environment using three profile
|
|
files. Each profile file is a shell script that can contain any
|
|
Qshell command. <img src="delta.gif" alt="Start of change">
|
|
See the <a href="variable.htm">Variables</a> article
|
|
for the complete list of supported environment variables.
|
|

|
|
|
|
<p><strong>Global profile file</strong></p>
|
|
|
|
<p>If the file /etc/profile exists, <strong>qsh</strong> runs it in
|
|
the current environment when you login. It is typically maintained
|
|
by an administrator to set system-wide defaults for all users. This file should be secured by
|
|
setting the public authority to read and execute.</p>
|
|
|
|
<p>Here is a sample /etc/profile file:</p>
|
|
|
|
<pre>
|
|
# Sample /etc/profile file
|
|
export PATH=/usr/bin:
|
|
</pre>
|
|
|
|
<strong>Profile file</strong>
|
|
|
|
<p>If the file .profile exists in the user's home directory,
|
|
<strong>qsh</strong> runs it in the current environment when you
|
|
login. It is used to customize your login environment.</p>
|
|
|
|
<p>Here is a sample .profile file.</p>
|
|
|
|
<pre>
|
|
# Sample .profile file
|
|
export ENV=$HOME/.qshrc
|
|
export PATH=$PATH:$HOME/bin
|
|
</pre>
|
|
|
|
<strong>Environment file</strong>
|
|
|
|
<p>If the file specified by the expansion of the <strong>
|
|
ENV</strong> variable exists, <strong>qsh</strong> runs it in the
|
|
current environment when starting an interactive shell. The
|
|
environment file is typically used to set aliases, define
|
|
functions, or set options for an interactive shell session.</p>
|
|
|
|
<p>Here is a sample environment file:</p>
|
|
|
|
<pre>
|
|
# Sample environment file
|
|
PS1='$PWD'
|
|
</pre>
|
|
