Hi Eric,
It can be done with perldb, but have you considered using
Devel::ptkdb? Devel::ptkdb gives you a nice, graphical, debug
environment. I just created a hash with 10 000 elements and
the debugger happily displayed it in the expressions window.
I could scroll from beginning to end.
As the name implies, Devel::ptkdb requires PerlTk. For me, it
was a good excuse to install Tk, which I was going to try anyway.
If you are determined to use perldb, here's how I would dump
%ENV to a file:
C:\My Documents\Perl\Test>perl -de 123
Default die handler restored.
Loading DB routines from perl5db.pl version 1.07
Editor support available.
Enter h or `h h' for help, or `perldoc perldebug' for more help.
main::(-e:1): 123
DB<1> O pager='>dbg.txt'
pager = '>dbg.txt'
DB<2> |X ENV
or if you prefer to setup the file like a log file, use append mode:
DB<3> O pager='>>dbg.txt'
pager = '>>dbg.txt'
DB<4> |X ENV
HTH,
Jonathan D Johnston
