Technical Diary - With Andrii Grytsenko

Under cover you can find some trick and script to check perl module installation.

To figure out whether perl module is installed at the system. Run:

perl -M<module_name> -e 1

if command return an error or NOT 0(zero) then module is not installed at the moment.

Here is also perl script which help you check a lot of modules:

#!/usr/local/bin/perl

my @modules = qw (put your modules here separated by space without any quotes);

foreach my $module (@modules){
print $module,"\t";
my $result=system("perl -M$module -e 1");
print "Installed" if (!$result);
print "\n";
}
