..but.. what are you asking about? to have the best from perlmonks you must learn to show some effort, asking clear questions with more information as you can: see How do I post a question effectively? and How (Not) To Ask A Question.

If you have code or commandline question see Short, Self-Contained, Correct Example

At glance it seems you have a problem calling Perl: in Linux like environments perl is called or via shebang #!/path/to/perl at the top of the script, or directly in bash like perl /path/to/script.pl

What I see is bash complaing the use command is not found. use is Perl stuff. To use module in the command line, let's say a perl oneliner you: perl -MModule::To::Use  -e '..oneliner..'

PS cross posting it is not prohibited here at BUT it is considered polite to mention that your question is a crosspost. Be kind if you want kind replies!

Anyway, is your first post; many things to learn! welcome!
