bash shell scripting substring

You can do it this way:

case "$VAR" in  *UAT*)   # code when var has UAT  ;;esac

bash shell scripting substring

The classic way, if you know ahead of time what string you're looking for, is a case statement:

case "$VAR" in*UAT*) : OK;;*)     : Oops;;esac

You can use an appropriate command in place of the : command. This will work with Bourne and Korn shells too, not just with Bash.
