I am new to this shell scripting....
I have a file which contains list of users. This files get updated when new user comes into the system.
I want to create script which will give a table containing unique list of users. When I say unique, it means script should match table while parsing user file list.
E.g.
List-----
User1
User2
User1
User3
User4
User1
The script output should be a list with
User1
User2
User3
User4
Thanks
