Linux

NOTE: an alternative to this script is:

command | grep –color ‘searchwords’

But lets say you dont want colors, or dont have a color terminal (because your stuck in the 80s 90s) then this is for you


Find a line you want and append extra text to its right so it stands out from the output

This will keep the output the same it will just append to the line that has the finding in it.

textoutput | awk ‘{ if( $1 ~ /SearchItem/) { print $0, “<===== found you”} else {print $0}}’

EXAMPLES:

Find rpool in zfs listing and make it standout:
zfs list -o space,compressratio,refer | awk ‘{ if( $1 ~ /rpool/) { print $0, “<===== found you”} else {print $0}}’

BONUS:
Looking for multiple things, how to make several things standout – using an OR – kind of like with grep or egrep.
Asking a program to find you item1 or item2, will find both item1 and item2.
Looking for multiple things
 
command | awk ‘{ if( $1 ~ (/item1/ || /item2/)) { print $0, “<===== found you”} else {print $0}}’
command | awk ‘{ if( $1 ~ /item1/) { print $0, “<===== found you”} else {print $0}}’
