In addition to the other resources mentioned in this thread, I would suggest the best document to read before going any further with Perl would be perlintro, which contains a section about writing subroutines. The value in perlintro is that it contains just enough on a broad range of Perl topics to inform the rest of your progress toward learning the language, yet takes less than a half hour to read in its entirety.

Learn Perl in about 2 hours 30 minutes is another gem; one that the Mojolicious project lists in its documentation as reference material for people newly coming to Perl.

perlintro takes 20-30 minutes to read. Learn Perl in about 2 hours 30 minutes takes...well, 2 hours and 30 minutes. But the sections on subroutines take about 5 minutes total, and should help you to come to a better understanding.

For your specific case, you need something like this:

sub SSHApp { my ($MyUser, $MyPass, $MyIP) = @_; # ...the rest of your code goes here. # You probably need: # my $output = $ssh_1->cmd('sh version'); return $output; }

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
