how to cntl^c in a script
can anyone please let me know how I can terminate a command Ex:"truss filename.truss.txt -p pid" after letting it run for 2sec in a korn shell script.In other words how can we emulate cntl^c in a script??

Assuming you executed the truss command in
background in the script, you can try...

...
truss ... &
TRUSSPID=$!
sleep 120
kill -2 $TRUSSPID

...basically, send SIGINT to the PID of the
truss process. Note however, I have not tested
this.

Thanks a lot for you prompt response..
I am not executing this command in the background.

Can I do the following??

mycomm='truss filename.truss.txt -p pid'
sleep 2
kill -2 $mycomm

By the way,Is kill -2 equivalent to cntl^c on keyboard??

You can not do what you've typed to achieve what you want, as they will be executed in a sequence, not parallelly. Try this i
nstead:

Code:

(sleep 2; kill -2 `ps | awk '{print $6" "$1'} | grep "^truss" | awk '{print $2}'`) | truss filename.truss.txt -p pid

Yes, kill -2 is the same as [CTRL+C] on the keyboard.
