Grep or Awk from a non-terminating program

ibrahimelkadi · #1 12-28-2009

Hey all,

Does anybody know how to grep or awk from a non-terminating program. For example the program top which displays the process cpu usage, idle %,...etc. I was wondering if I can grep or awk certain fields from it.

The other thing I was wondering about is how to insert a CTRL-C command in a shell script, is it possible??

Thanks in advance

Yes,
you can. Just send the input to the awk interpreter.

You can run top in batch mode (so you don't need to send it Ctrl+C) On Linux it would be something like this:

Code:

top -bn10 | awk ...

kill -INT pid
