FreeBSD top(1) – processes within specific jail

On FreeBSD top(1) utility, although having much less command line switches and options is in fact much more powerful than one that comes with your favorite Linux distribution.

Maybe one day I decide to publish an in depth write up about it but until that day comes here’s one hint. To show only processes that are running within specific jail launch top:

top

press:

J

enter your jail name:

examlejail

Voila, you have only processes within that specific jail listed. To show up processes from all jails, instead of typing in name of the jail simply type in + sign.

Now that I better think about it, to learn more about top:

man 1 top

FreeBSD man pages are also far better than Linux ones ;-)
