查看已安装PERL的模块

1、perldoc perllocal

 

2、推荐pmtools里的pminst命令
   http://search.cpan.org/src/MLFISHER/pmtools-1.01/pminst

 

3、编写如下标本

#!/usr/bin/perl
use strict;
use ExtUtils::Installed;

my $inst= ExtUtils::Installed->new();
my @modules = $inst->modules();

foreach(@modules)
{
        my $ver = $inst->version($_) || "???";
        printf("%-12s --  %s\n", $_, $ver);   
}
exit ;
