Re^2: How to limit CPU utilization by ANY process with a perl script?

Hmm, I think I might be misunderstanding what your one-liner is doing, but isn't the fourth element of @F %MEM, not %CPU?

USER     PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
marc    9764  0.0  1.9  85544 40380 ?        S    15:47   0:07 pidgin

$ ps aux | perl -lane 'print if $F[3] == 1.9'
marc    9764  0.0  1.9  85500 40376 ?        S    15:47   0:07 pidgin

And you didn't even know bears could type.

That's true. In my case, the 4th element is for the CPU. I guess ps gives a different output depending on your Linux flavor.	[reply]
