<hr/>**评论：**<br/><br/>drvd: <pre><p>Most probably you didn't export it :-)</p></pre>gohacker: <pre><pre><code>gohacker:~/test$ ./test
Home dir : /home/gohacker
PS1 var :
gohacker:~/test$ export PS1
gohacker:~/test$ ./test
Home dir : /home/gohacker
PS1 var : \[\e]0;\u@\h: \w\a\]${debian_chroot:+($debian_chroot)}\u@\h:\w\$
</code></pre></pre>digitalyatri: <pre><p>set command shows both HOME and PS1 whereas env command shows HOME only</p>
<p>Makes sense, looking at the following</p>
