[TriLUG] OT - Reg Exp question.

[Andrew Perrin]

Works for me:


aperrin at che:~$ perl -de1

Loading DB routines from perl5db.pl version 1.28
Editor support available.

Enter h or `h h' for help, or `man perldebug' for more help.

main::(-e:1):   1
   DB<1> print 'good morning' if 0 =~ /^[0-9][-0-9,]*$/;
good morning
   DB<2>
