Hi,
can some ppl test and tell me if this is correct ans? pls..
my linux soft. is giving trouble.

whats wrong with this script?

thanks

Ques. Write a bash script that kills all the processes executing a certain command at a certain moment in time. For example, kill all processes running mail. Unless you have a super user privilege, you can kill only your own processes.

Ans:

#!/bin/sh

kill `ps -ef | grep $1 | awk '{ print $2 }'`

Homework. Again.

Can someone wield the ban-stick on this guy?

Maybe put in a loop to kill each individual process? Otherwise you are sending a list of all the processes to kill at once.

#!/bin/bash
for x in `ps -ef|grep $1|awk '{print $2;}'`
do
kill $x;
done

Test my answer? Look at the killall utility. We're not a service here. Especially when it's obviously just a homework assignment.

xargs is good for this too.

you have enough clues now to work it out
