This script emulates a (really ugly) perl shell within your bash (or wathever) session. I like it to quickly test a few regexps or a function.
- #!/usr/bin/perl -wn
- # the -n switch gives us a loop around the script. the BEGIN block is
- # only executed once. it sets up our prompt and turns off the signals
- # that could interrupt the script
- BEGIN {
- # turn off control keys
- $SIG{$_} = 'IGNORE' for keys %SIG;
- # let the user know how to get off this crazy thing.
- print "\n\tType\e[1m exit\e[0m when you are ready to stop.\n";
- $history = 1;
- sub prompt {
- print "\n", $ENV{USER}, '@perl-shell[', $history++, ']>';
- }
- prompt;
- }
- # the body is executed over and over (each time <> is given). all we
- # do is eval the body, and voila, perl-shell behavior
- eval;
- $@ and warn $@; # give perl errors back to the user
- prompt; # print a fresh prompt with updated history
- END { print "\n\t\tBye!\n\n" }

Ho nice, I got it via a friend on IRC but couldnt tell where it was from. Are you the author of this script ? If so, good job, it helped me a few times
hey, there, Ozh. back after awhile. it's sort of mine, i got the original idea/skeleton from tim maher who was running the seattle perl users group.
