problem killing a process with its pid

[Richard Yang]

Thank you :)
actually,
kill -9 $(cat /var/run/natd.pid |cut -d" " -f1)
in a script
will work... (4 hours of work for this....)


for some reason, 'kill' doesn't think 'cat natd.pid' is a valid pid.
i have to specially cut the first part out to get it straight
i am using csh

i tried your suggestions just now and below are the result

kill -9 `cat /var/run/natd.pid`
kill: Arguments should be jobs or process id's

kill -9 `cat /var/run/natd.pid|cut -d" " -f1`
kill: Arguments should be jobs or process id's

what do you think is the reason?
i most certainly flunk my shell... hehe
