Hi,
I would like to know how can I display the unique/distinct file name from ls in linux. Will appreciate if you could let me know the exact command in order to get the below mentioned result.

The distinct output should only list the starting name list only for example only one charlie, only one tango and only one alpha like below one :

[ncell@informatica-srv1 test]$
-rwxrwxrwx 1 etl etl 937 Sep 13 22:00 charlie13150913_111_222629.unl
-rwxrwxrwx 1 etl etl 186 Sep 11 01:44 tango20150911_117_112263.unl
-rwxrwxrwx 1 etl etl 186 Sep 21 01:44 alpha20150921_123_033924.unl

Above output is what i am looking for, Again I need only one charlie, tango, alpha from the below mentioned output

[ncell@informatica-srv1 test]$ ls -ltr
