Im creating a script that i am executing every night at 03.00 that will kill all screens that has been running longer than 3 weeks.

anyone done anything similar that can help? If you got a script or suggestion to a better method please help by posting :)

I was thinking maybe somthing like this.

First do a dump to textfile

ps -U username -ef | grep SCREEN >> dump.txt

then do a loop running through all lines of dump.txt with a regex and putting pid of the prosseses with STIME > 3weeksago in a array.

then do a kill loop on the array result.
