[rt-users] Regex in scrip won't match multi-line strings

[Peter Nikolaidis]

Apparently I'm still doing something wrong and regex is kicking my butt.

Sample message body:
-----------------------------------------
* Stopping Asterisk PBX: asterisk
...done.
* Starting Asterisk PBX: asterisk
...done.
-----------------------------------------

Patterns I've tried:
-----------------------------------------
1:
(($self->TicketObj->Subject =~ /Cron \<root\@pbx\> \/etc\/init\.d\/asterisk
restart/) && # Successful cron jobs.
($self->TicketObj->Body =~ /\* Starting Asterisk PBX\:
asterisk\n\.\.\.done\./m)

2:
(($self->TicketObj->Subject =~ /Cron \<root\@pbx\> \/etc\/init\.d\/asterisk
restart/) && # Successful cron jobs.
($self->TicketObj->Body =~ /\* Starting Asterisk PBX\:
asterisk.*\.\.\.done\./ms))
3:
(($self->TicketObj->Subject =~ /Cron \<root\@pbx\> \/etc\/init\.d\/asterisk
restart/) && # Successful cron jobs.
($self->TicketObj->Body =~ /^\* Starting Asterisk PBX\:
asterisk.*\.\.\.done\.$/ms)) ||
-----------------------------------------

Any ideas?

Thanks,

Peter
