G'day Rolf,

Update: I posted a solution but later found it didn't work with commands that output multiple lines (e.g. ls, ps, etc.). Here's a new solution that doesn't have that problem. The original also had a portability issue: this one doesn't. (The spoiler below contains the original solution.)

My .perldb contains:

$ cat ~/.perldb for (qw{pwd date ls ps}) { $DB::alias{$_} = 's{^($_.*)$}{chomp(my $out = qx{$1}); print {$DB::OUT} $out} +e'; }

Obviously, substitute qw{pwd date ls ps} with your qw/commands/. See perldebug - Debugger Customization for a description of %DB::alias.

Here's a test run:

$ perl -d -e 1 Loading DB routines from version 1.33 Editor support available. Enter h or `h h' for help, or `man perldebug' for more help. main::(-e:1): 1 DB<1> pwd /Users/ken/tmp DB<2> date Sun 9 Sep 2012 18:12:43 EST DB<3> date "%Y-%m-%d" date: illegal time format usage: date [-jnu] [-d dst] [-r seconds] [-t west] [-v[+|-]val[ymwdHMS +]] ... [-f fmt date | [[[mm]dd]HH]MM[[cc]yy][.ss]] [+format] DB<4> date "+%Y-%m-%d" 2012-09-09 DB<5> ls -l total 30824 ... drwxr-xr-x 7 ken staff 238 14 Jun 20:23 zip_test DB<6> ps -ef UID PID PPID C STIME TTY TIME CMD ... 501 74528 74527 0 23Aug12 ttys007 0:00.04 -bash DB<7> q $

The typo (date "%Y-%m-%d") was accidental but I left it in just to show that the mistake was handled in a reasonable fashion.
