AARRRGH!! I've been at this regex for 4 hours, now. Can someone tell me why this doesn't work? The data: 
SLOT 0 (RP/LC 0 ): Route Processor
SLOT 2 (RP/LC 2 ): 1 Port Packet Over SONET OC-12c/STM-4c Single Mode
SLOT 3 (RP/LC 3 ): 1 Port Packet Over SONET OC-12c/STM-4c Single Mode
SLOT 4 (RP/LC 4 ): 1 Port Packet Over SONET OC-12c/STM-4c Single Mode
SLOT 7 (RP/LC 7 ): 1 Port Packet Over SONET OC-12c/STM-4c Single Mode
SLOT 16 (CSC 0   ): Clock Scheduler Card(8)
SLOT 17 (CSC 1   ): Clock Scheduler Card(8)
SLOT 18 (SFC 0   ): Switch Fabric Card(8)
SLOT 19 (SFC 1   ): Switch Fabric Card(8)
SLOT 20 (SFC 2   ): Switch Fabric Card(8)
SLOT 24 (PS A1   ): DC Power Supply(8)
SLOT 26 (PS B1   ): DC Power Supply(8)

I want to match all lines, EXCEPT those containing, "Clock", "Switch", "Power", " Processor". Here's the regex: 
 if ($rtr_diag =~ m/^(SLOT.*$)/ && 
! /(Processor.*$)/|/(Switch.*$)/|/(Power.*$)/|/(Clock.*$)/ )

{ do stuff}

What's going on, here??? I've tried [^...]; didn't work. Along with every other way, but the right way, apparently.
