List all files and reject any that have any lower-case chars.
Code:
ls | grep -v "[a-z]"

In what way did it "not work"? Show exactly what you did, word for word, letter for letter, keystroke for keystroke, and show exactly what happened afterwards.

It works fine here:

Code:
$ mkdir mytest ; cd mytest
$ touch abc.IDS XYZ.IDS
$ ls | grep -v "[a-z]"
XYZ.IDS

That is because ls -l shows a lot more than just file names, and it ends up finding lowercase letters in other parts.

If you wanted to filter ls -l's output, you need a tool that understands columns, like awk:

Code:
# Print all lines where the last column does NOT contain lowercase letters
ls -l | awk '!($NF ~ /[a-z]/)'

...but this won't work for filenames with spaces.
