How to list all installed Perl modules
 
How do I list all the Perl modules installed in my machine? I know perl -l 'use Module::Name;print"okay"' will tell me about
a particular module, but I want a complete list, so I can maybe redirect
it's output to a file.

perl -MFile::Find=find -MFile::Spec::Functions -Tlwe \
'find { wanted => sub { print canonpath $_ if /\.pm\z/ }, no_chdir => 1 }, @INC'

Perl: query about the module installed
 
Use command to check for Net::Ping module installed:

perl -MNet::Ping -e "print \"Module installed.\\n\";"

here Net is package name and Ping is module name under package Net.

'Module installed.' message will be displayed if Package::Module installed.

You can try
perl -MNet::Ping -e 1
If you get error message immediately then the module not installed!

thanks
 
I had to register here just so I could say thanks for the command to pull out all installed perl modules.

Very nice indeed. Thank you again!

Use the following command and type "l" in the prompt to list all installed perl modules.

instmodsh
Thanks.

And another thanks from me. This just addressed a problem in like 30 seconds. All hail LQ (and google)!

Works great , thanks

But I have a question , in WindowsXP (active perl 5.8) command "perldoc perllocal" works , but in linux it doesnt , any reason for this.

One more way to find is,

$ instmodsh

cmd? l

Available commands are:
l - List all installed modules
m <module> - Select a module
q - Quit the program

cmd? l

Installed modules are:
Image::Magick
OBEXFTP
Perl
SWF

cmd? m perl

Available commands are:
f [all|prog|doc] - List installed files of a given type
d [all|prog|doc] - List the directories used by a module
v - Validate the .packlist - check for missing files
t <tarfile> - Create a tar archive of the module
h - Display module help
q - Quit the module

perl cmd? f

Outputs all the installed modules

For reference you can use this as well:
Code:
pmall
Which give this output:
Code:
Crypt::Blowfish (2.12) - Perl Blowfish encryption module
Crypt::DES (2.05) - Perl DES encryption module
Math::PariInit - load C<Math::Pari> with specified $primelimit and $initmem.
Math::Pari (2.01080605) - Perl interface to PARI.
Time::HiRes (1.9721) - High resolution alarm, sleep, gettimeofday, interval timers
Digest::SHA1 (2.13) - Perl interface to the SHA-1 algorithm
Digest::MD2 (2.03) - Perl interface to the MD2 Algorithm
YAML (0.73) - YAML Ain't Markup Language (tm)
CPAN::Meta (2.112621) - the distribution metadata for a CPAN dist
...
I usually include a text file containing the output of this command to my backups, this will help a lot in case of disaster recovery.
