no, not 'like so', but rather like so:
Code:
ls -l | tr [a-z] [A-Z]

Thanks !! Guys ...

It should. I tested it and it worked:

# ls -l /opt/ | tr [a-z] [A-Z]
TOTAL 12
DRWXR-XR-X 9 ROOT ROOT 4096 JUL 17 12:45 VIRTUALBOX
DRWXR-XR-X 9 ROOT ROOT 4096 JUN 11 07:05 SPLUNK
DRWXR-XR-X 6 ROOT ROOT 4096 JUN 6 11:36 SUN-JRE-BIN-1.6.0.13

Make sure there is something (files) in your current directory.

For the "tr" to work in all circumstances you need quotes:

ls -l /opt/ | tr '[a-z]' '[A-Z]'
