kill: bad argument count
Hi Team,

I am getting the below error when running the script. Please let me know how to solve this error.
Code:
start_WFA.sh[9]: kill: bad argument count

Below is the Script:
Code:
#!/bin/ksh
kill -9 `ps -ef|grep classpath |grep "/apps/ap" |grep -v "Xmx" |grep $LOGNAME |awk '{print $2}'`

Thanks,

And, how does kill respond if you just type kill -9 on the command line?
What's the output of that command in back-ticks?

Most likely, no process qualifies for being killed. Try
Code:
PIDS=`ps -ef|grep classpath |grep "/apps/ap" |grep -v "Xmx" |grep $LOGNAME |awk '{print $2}'`
[ -n "$PIDS" ] && kill -9 $PIDS

Check for the below command output.
Code:
ps -ef|grep classpath |grep "/apps/ap" |grep -v "Xmx" |grep $LOGNAME |awk '{print $2}'

This must return something valid for kill. i.e. integer/process_name in your case.

The issue resolved by using the above command

We are getting the output for the below command
--------------------------------------
Code:
appodev:>ps -ef|grep classpath |grep "/apps/ap" |grep -v "Xmx" |grep $LOGNAME |awk '{print $2}'
15577

------------------------------------------

Can you tell me what this command do ?
Code:
[ -n "$PIDS" ] && kill -9 $PIDS


Thank you all for your quick help.

If you aren't aware of their existences, most systems have pgrep and pkill, which in many cases can replace a fragile, underspecified pipeline with a more rigorous and portable simple command.

The PIDS variable contains a list of pids, which qualify for being killed. Now if the variable is NOT empty ( [ -n "$PIDS" ] ) then kill them all. && is a logical AND which can be used as a short form of an if-then-fi construct.
