I failed googling for this OS ... could you provide a link?

update

you most likely mean Ubuntu, but there are so many flavors out there ...

`apt-get install libexpect-perl libterm-vt102-perl libdata-dumper` above are installed. Is there any way to check if module is loaded and installed on perl ?	[reply] [d/l]

I usually do `perldoc -l Data::Dumper` at the command line. Just tried it on one of my systems, and I got `/usr/lib/x86_64-linux-gnu/perl/5.26/Data/Dumper.pm` [download] in response. To find out the version, I `grep` for version in that file .. $ grep -i '^version' /usr/lib/x86_64-linux-gnu/perl/5.26/Data/Dumper.p +m Version 2.167 (January 4 2017) $ [download] Conversely, if the `perldoc` approach doesn't turn anything up, either the module isn't installed -- or it doesn't have POD. Then you could try using it in the debugger: `$ perl -MData::Dumper -de 1 Loading DB routines from perl5db.pl version 1.51 Editor support available. Enter h or 'h h' for help, or 'man perldebug' for more help. main::(-e:1): 1 DB<1>` [download] If that loads OK, then the module does exist. If Perl can't find the module, it'll complain.

See the FAQ: How do I find which modules are installed on my system?	[reply]

There are many ways: `perl -MModule::Metadata -le'$i=Module::Metadata->new_from_module($ARGV +[0]);print $i->{filename}' Data::Dumper` [download] `perl -MExtUtils::Installed -le'$i=ExtUtils::Installed->new;print grep +/$ARGV[0]/, $i->files("Perl")' Dumper` [download] `perl -MFile::Find -le'find(sub{print $File::Find::name if /$ARGV[0]/}, +$_) for @INC' Dumper` [download]	[reply] [d/l] [select]

I use whichpm. It's a module on its own and needs to be installed.	[reply]
