filter top result

Question

I'm using macOS Sierra and I would like to log a process with the top command and store all the information in a file. I'm using the following command:

top | grep --line-buffered "PROCESS" > test.txt

This perfectly works, but I would like to select only certain columns as the reseults:

PID
Memory Usage
CPU Usage
Network Usage
Disk Usage

Is there a way to filter the top result and select only the columns of my interest?

You can run this command in a loop.

top -l 1 | grep "PROCESS" | awk '{print $1,$2}' >> test.txt

Use awk to select the respective columns you want to include in your logs. For example, $1 is the first column, $2 is the second and so on.

Ok, now the command works, but how to run it once a second? – user1849976 Sep 29 '16 at 17:21
Try the watch command or sleep in bash. See: http://unix.stackexchange.com/questions/10646/repeat-a-unix-command-every-x-seconds-forever – faadi Sep 29 '16 at 17:26

can use awk '/PROCESS/{print $1,$2}' instead of grep + awk combo :) – Sundeep Sep 30 '16 at 04:51
@Sundeep yea that should work as well – faadi Sep 30 '16 at 18:48
@Sundeep thank you for your tips, it works :) – user1849976 Oct 01 '16 at 10:50
