#!/bin/bash echo -n "Please enter your name: " read -e USER if grep -q "$USER" namelist then echo $USER else echo "Name does not exist" fi In namelist file I added Rony, Macrony and karan. While both rony and Rony are accepted, for the other 2 names they are even case sensitive and do not accept macrony or Karan. Even prabhakaran and karunakaran are rejected. Why rony is not case sensitive is still a mystery. -- As a proper list etiquette..... Please trim your replies. Avoid cross posting to other lists.
