Hi I have an output which is of the following format.... which is the output of ps command is unixπ

nsmail   309   308  0 19:17:05 ?        0:00 /san/ms01/ms/mailMove/ActivityServer/bin/activityServerCtl ms01
 nsmail   308      1  0 19:17:05 ?        0:00 /san/ms01/ms/mailMove/ActivityServer/bin/activityServerCtl ms01
 nsmail   311   308  0 19:17:05 ?        0:00 /san/ms01/ms/mailMove/ActivityServer/bin/activityServerCtl ms01
 nsmail   313   308  0 19:17:05 ?        0:00 /san/ms01/ms/mailMove/ActivityServer/bin/activityServerCtl ms01
 nsmail   316   308  0 19:17:05 ?        0:00 /san/ms01/ms/mailMove/ActivityServer/bin/activityServerCtl ms01
 nsmail   310   308  0 19:17:05 ?        0:00 /san/ms01/ms/mailMove/ActivityServer/bin/activityServerCtl ms01
 nsmail   315   308  0 19:17:05 ?        0:00 /san/ms01/ms/mailMove/ActivityServer/bin/activityServerCtl ms01

I use "split" and "foreach" command to analyse the output line by line.

I Need your help in extracting the PID (values in bold) from each line. Please add your comments.

It will be helpful if i can get to know the extract PPID also

Thanks in advance
Fahad

set demo "nsmail 45 66 Hello World"
regexp {[[:alnum:]]+ ([[:digit:]]+) ([[:digit:]]+)} $demo all pid ppid
puts "pid is $pid and ppid is $ppid"
