NAME pmeth – show a Perl class’s methods DESCRIPTION Given a class name, print out all methods available to that class. It does this by loading in the class module, and walking its symbol table and those of its ancestor classes. A regular method call shows up simply: $ pmeth IO::Socket | grep ‘^con’ confess…
NAME pmerr – translate Performance Co-Pilot error codes into error messages SYNOPSIS pmerr code … pmerr -l DESCRIPTION pmerr accepts standard Performance Co-Pilot (PCP) error codes via the code argument(s) and generates the corresponding error text.
