Monitor memory fine-grained usage (e.g. firefox)

watch "awk '/Rss/{sum += \$2; } END{print sum, \"kB\"}' < /proc/$(pidof firefox)/smaps"
Sometimes top/htop don't give the fine-grained detail on memory usage you might need. Sum up the exact memory types you want

What Others Think

Was this submitted for the contest? It's missing the CLFUContest tag

Interesting. I tagged it "CLFUContest, watch, awk, pidof" and none of the tags showed up. I edited and re-tagged it with the same set of tags and they're still not showing up.

Turns out that I type faster than the tag auto-complete could respond, so I had to type each tag, wait a second for it to turn into an actual tag, click on the tag, type the next tag, wait, repeat. I think I've got all the tags in there now. Thanks, sqweek, for catching that.

No worries. You taught me something new about /proc, would have been a shame for this to miss the contest :)

Some things return multiple PIDs, eg: pidof firefox on my machine returns two pids. So I get "ambiguous redirect". Or if there are multiple commands: pidof ssh this command will fail. It probably requires a for or while loop. Even so, it's a handy concept.

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
