Another way of achieving the same effect is:
ps ax | fgrep cron | fgrep -v fgrep
Heh. This brings up one of my favourite Unix interview questions.
How do you do the same thing for a (possibly long running) grep command? That is, in the example above, instead of cron, how do you get exactly one line of output if the process in question were a grep?
[/home/soumen] $ grep asdfasdf & [1] 2974 [/home/soumen] $
[1]+ Stopped grep asdfasdf [/home/soumen] $ ps -eaf |grep grep soumen 2974 2643 0 22:48 pts/2 00:00:00 grep asdfasdf soumen 2976 2643 0 22:48 pts/2 00:00:00 grep grep [/home/soumen] $ ps -eaf |grep grep |grep -v "grep grep" soumen 2974 2643 0 22:48 pts/2 00:00:00 grep asdfasdf [/home/soumen] $
Is this the right approach?
