How to find the installed perl modules

[Arun123]

Hi Team,

How can I find the currently installed perl modules in my hp-ux 11.11i system. I am doing an OS upgrade and need to know which modules are currently installed in my system..?

[Tim Nelson · Accepted solution]

#!/usr/bin/perl

use ExtUtils::Installed;
my $instmod = ExtUtils::Installed->new();
foreach my $module ($instmod->modules()) {
my $version = $instmod->version($module) || "???";
print "$module -- $version\n";
}

hi,

swlist -l fileset | grep -i perl

Hi:

Tim's suggestion will do what you want. Using the standard SD tools ('swlist' in the case) is meaningless for Perl modules.

Hi Tim/James,

I am not good in perl and it gives following error.

syntax error in file test at line 2, next 2 tokens "use ExtUtils"
Missing $ on loop variable at test line 4.

Hi Arun:

Did you copy-and-paste exactly what Tim offered?

I suspect you didn't and that the script you are running does *not* begin with the correct interpreter line.

The first line of the file should be:

#!/usr/bin/perl

...or:

#!/usr/bin/env perl

Regards!

Hey;

A google search on "perl list modules installed" will be very helpful.

There's a freeware utility called list-modules.pl (also google-searchable) which will generate a web page containing all the installed modules.

I hacked it to get rid of all the html crap as I like command line stuff. It's easy enough to do. If you need it, let me know and I can paste it in for you.
