Question

I want Only String

something0^^^something1^^^something2

by removing

^^^something3

How can i get it in shell script

Answer 1

Using pure BASH:

s='something0^^^something1^^^something2^^^something3'
echo "${s/^^^something3/}"
something0^^^something1^^^something2

OR you can just delete everything after last ^^^:

echo "${s%^^^*}"
something0^^^something1^^^something2
