How to remove characters from a string

Question

How to remove characters from a string like this

"i have string in a variable say string="auto.deploy.active = yes", i want to take out everything after "=" and store that extracted string in another variable using a shell script"

Is the string inside a file, pipe, or variable? – Socowi Feb 15 '19 at 06:48 — Socowi, Feb 15 '19 at 06:48

You can use awk

command is:

$ var1=`echo "auto.deploy.active = yes" | awk -F"=" '{print $1}'` ; echo $var1
auto.deploy.active 

$ var2=`echo "auto.deploy.active = yes" | awk -F"=" '{print $2}'` ; echo $var2
yes
