Stay in the loop…

Follow the Tweets.

Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Use top to monitor only all processes with the same name fragment 'foo'

Like command 10870, but no need for sed

top accecpts a comma separated list of PIDs.

top $(pgrep foo | sed 's|^|-p |g')
2012-06-14 15:13:00
User: michelsberg
Functions: sed top
5
pgrep foo

may return several pids for process foobar footy01 etc. like this:

11427

12576

12577

sed puts "-p " in front and we pass a list to top:

top -p 11427 -p 12576 -p 12577

Know a better way?

If you can do better, submit your command here.

Nice!

Just read top's manpage again. top -p PID1,PID2,PID3 is possible, too:

top -p $(pgrep -d , foo)

I like it, @michelsberg ...now we just need a version that will find new instances of "foo" as they start in the background...
