How to kill top command using script?
Hi all,

I am using top command in my script to redirect output to temp file. I used kill -9 `ps -ef|grep top|grep -v grep|awk '{print $2}'` to kill top command in my script, but it is not working? Can you please tell how to kill top command in my script?

Why do you have to kill the top command in such manner, how are you using that command, can we see the relevant snippet of this script ? Else, you can always use "pkill -9 top" but be careful, this will kill any process with " * top * " pattern in the name, it's pretty harsh, so watch out.

If you are running it in the background, just store $! in a variable just after starting it, and kill $! when you need to.

top has options to tell how many iterations to run; perhaps you should be using those instead.

Don't use kill -9 unless you know what you are doing.

Use the -f option to top...it outputs one display to the named file and exits automatically.

Code:
top -f /path/to/outfile

depends on what version of top
in my end, the option is
-b (for batch)
and -n 1 (for 1 iteration)
