in thread Find perl module version from command-line

The extra output is being generated by the CPAN module itself. I checked out the code on mine and I don't see any conditionals or anything that could be passed to supress that output. So, the simple answer is to grep for what you want or use CPAN | tail +5 because I don't think there's much you can do from the perl side that doesn't require putting more effort into it than it's worth.

    I know this is kind of an old thread, but I was wondering if anyone has any code that will recursively go through a directory structure and find ALL the PERL modules and then print out the version. My Red Hat Linux distro has /usr/local/lib/perl5 and then the sub-dirs 5.8.5 and site_perl. How would I sweep through these two sub-dirs, find all the .pm files, for example, and then have it give me the VERSION if a VERSION variable exist in the .pm file? The reason I ask is I have 4 machines which I must compare VERSIONs on. So if I can get the output into 4 individual files I can easily import the data into a spreadsheet and compare. I have a small bash script that seems to work, but I'm looking for an efficient PERL method. I am just learning PERL i.e. I'm a few pages into the 5th ED. of the O'Reilly book, so the coding required is still a bit over my head, yet I have this task to complete for the boss man. Any help you can offer would be greatly appreciated.

      How about ack '^\s*\$VERSION'? See App::ack.

      Also, instead of using Excel, you might want to use sort and diff to find the differences between the machines.

        Or just
        grep 'VERSION' $(find . -name \*.pm -type f)
        which uses standard Unix tools.

        Thanks. I will try and see if I can get that. App::Ack is not in my current PERL install. All I have in App is something called Prove. We have this weird convoluted process to get files from the Internet to the private systems.

      Umm, I thought I was logged in when I posted ^4 of this thread. So ^4 and ^5 are from user geelsu. Also, this PERL install is on a private network with no access to the Internet so I can even get to CPAN for example.
