How to output a string after a certain character?

Question

bash

I want to output only after the = sign

# grep 'ncore=' /opt/aliases.conf 
ncore=/home/firebird/db/firebird.fdb

or if someone is selenium in firebird, then maybe he will tell you how to derive the path to the base from the alias

Answer 1

$ grep 'ncore=' /opt/aliases.conf | sed 's/=/ /' | awk '{ print $2 }'
/home/firebird/db/firebird.fdb

Answer 2

sed -n 's/ncore=//p' /opt/aliases.conf
