Does anyone know if there is a way to filter the output of ps aux to
show only lines that have a value in the %CPU column higher than x - ie,
1.0, or 2.0, or something like that?


Thanks

For that, you need awk instead of grep.

ps aux | gawk '{ if ( $3 > 1.0 ) { print } }'

Never used awk... any chance you (or someone) could provide an example
of how to do this?


Also - would there be a way to get a running output (kind of like
tailing a log)?

ps aux | gawk '{ if ( $3> 1.0 ) { print } }'


Thanks Paul! Thats a huge help...

Now if I could just get a constantly updated output of this (like
tailing a live log), I'd be in heaven...


But if this is the best I can do, it is 1000 times better...

watch -n1 "ps aux | gawk '{ if ( $3 > 1.0 ) { print } }'"

Why would you use "if"? You can easily use this :


ps aux | awk '$3 > 1.0 {print}'
