Hi;

  What is the perl equivalent of a #!/bin/bash -xv?

  I'd like to have verbose (print each line prior to execution) and expand
each variable prior to execution while executing?

  How do I run perl in debug mode non-interactively, dumping every
variable
when it gets modified?

  How do I get the answers to either or both of these questions using
perldoc?

  Is there a perl builtin to do this?  If not is there a cpan module to do
this?  If so, how would I effectively search cpan for a topic such as
this?


Thanks,
Ken Wolcott
