Content-Type: text/plain; charset="gb2312"<br>
<br>
我的代码如下：<br>
#!/usr/bin/perl -w<br>
#<br>
use strict;<br>
use utf8;<br>
#use CGI qw/:standard/;<br>
use CGI qw/:all/;<br>
print header,<br>
start_html("Mailing list manager system page"),<br>
h1('Maillist&#31649;&#29702;&#31995;&#32479; '),<br>
start_form,<br>
"What are you doing?",<br>
popup_menu(-name=>'choose',<br>
-values=>[qw(select create delete modify)]),p,<br>
submit,<br>
end_form,<br>
hr;<br>
if(param()){<br>
if (em(param('choose')) =~ /select/){<br>
system "date";<br>
print `ls -l \$HOME`;<br>
＃system "ls -l \$HOME"<br>
}<br>
if (em(param('choose')) =~ /create/){<br>
system "date -u";<br>
<br>
}<br>
}<br>
<br>
其中时间能正确显示，但是，就是不能打印 ls -l $HOME 这行，换成 system "ls -l \$HOME"也不能打印，还希望各位老师能指教，谢谢！<br>
