command result as varible

Hi
I'm trying display only a few information from result returned by script.

My reslult is like:

PHP Code:



backends:0 commits:1837 rollbacks:3 read:0 hit:0 ret:0 fetch:0 ins:0 del:0 dbname:postgres

and I need display only backends:0 (and later make rrd file).

How to division result to part?

provided that backends is always the first field you can do this:

Code:

$ echo "backends:0 commits:1837 rollbacks:3 read:0 hit:0 ret:0 fetch:0 ins:0 del:0 dbname:postgres" | cut -d ' ' -f1
backends:0
