Using the Perl Debugger
Perl's debugger is a command line debugger, so while it's not
pretty, with buttons and little red lines for your breakpoints,
it can be pretty durn effective once you get used to it. This
isn't so much of a tutorial as a brief overview of the most common commands.
bash$ perl -d myscript.plThis will put you in the command line mode. It looks like:
main::(perl/test.pl:5): print "Just another perl monk\n"; __DB<1>__
Dissecting it, we have this information:
Module::(sub module)::function(physical file location:line number): current line of code;
now you can type in whatever you want to make your program proceed.
Know your command set!
