debugging multi-file scripts using perldb

[Gaurav Shah]

I'm using perldb to debug scripts that call functions from many
different files, which are included with the "require" command.

How do I set a breakpoint in a function, or at a line, that is found
in a file other than the main one?

Thanks in advance,

If the function has already been compiled, 'b funcname' will do it.
Of course, it may be in another package and hence 'b somepack::funcname'.

To switch to another source file to use its line numbers, use the
'f' command.

If the function hasn't been compiled yet, you can use
'b postpone funcname' to set a breakpoint on it when it is eventually
loaded.
