Version? Getopt::Long

[Mark J Fenbers]

I'm giving tech support to someone and suspect his version of
GetOpt::Long is older than mine. What simple test can be given on the
command-line to determine what version is being used on his computer?
Perhaps something like:

perl -MAppConfig -e' print_version()'

or something along those lines...

The canonical way is:

perl -MGetopt::Long -e 'print $Getopt::Long::VERSION'

Of course, that would depend upon the author of this module following
the convention of creating a package variable $VERSION with the
appropriate information.

.... which he does .

This will also work:

% perl -MGetopt::Long=3.00
Getopt::Long version 3.00 required--this is only version 2.34 ...
