You might find more interesting ideas by typing 'all modules' in the search box at the top of this page. ...and then hitting the return key ;) --DrWhy "If God had meant for us to think for ourselves he would have given us brains. Oh, wait..."	[reply]

The Module::ScanDeps module will recursively find all modules used by your scripts. It will also find all core modules, so you need to sort out what you do and don't need. `use strict; use warnings; use Module::ScanDeps; # insert your script(s) name(s) here my @scripts = qw/ myscript.pl /; my $hash_ref = scan_deps( files => \@scripts, recurse => 1, ); print $$hash_ref{$_}->{'key'}."\n" for sort keys %$hash_ref;` [download] Ideally though, you should just use CPAN to install the necessary modules.

%INC is your friend. Inspect it and see what it stores. Better yet is to just use the CPAN module and install them on the new machine. In general, if you think something isn't in Perl, try it out, because it usually is. :-) "What is the sound of Perl?

I need to figure out where all these modules reside to copy to the Linux system I use the following to get info about where a module is, what other modules it ends up loading, and its version: `#!/bin/sh perl "-M$1" -e 'print map { sprintf( "%20s : %s\n", $_, $INC{$_} ) } s +ort keys %INC; print "\n'$1' version : $'$1'::VERSION\n\n"'` [download] That being said, it's very important to look at where it is, before you decide to up and move it to a different architecture or OS. Take the following: Read more... (2 kB) Any of the components with the architecture in their name (in this example, 'darwin-thread-multi-2level', have compiled components, and cannot just be picked up and moved to the new server.
