Perl - Check a module is installed.md

If you want to quickly check if module is installed (at least on Unix systems, with bash as shell), add this to your .bashrc file:

alias modver="perl -e\"eval qq{use \\\$ARGV[0];\\\\\\\$v=\\\\\\\$\\\${ARGV[0]}::VERSION;};\ print\\\$@?qq{No module found\\n}:\\\$v?qq{Version \\\$v\\n}:qq{Found.\\n};\"\$1"

Then you can:

=> modver XML::Simple
No module found

=> modver DBI
Version 1.607
