how to set multiple white spaces (ex: tabs) as delimiters in bash's `cut`
- by Idlecool
I want to retrieve the cpu usage/free percentage from mpstat output. The bash cut can be used to retrieve such details but i dont know what should be the delimiter viz.
[idlecool@archbitch proc]$ mpstat | grep "all" | cut -d '$x' -f11
what should be $x so that i can skip white spaces and select value corresponding to %idle?
Output of mpstat:
[idlecool@archbitch proc]$ mpstat
