If you get back "AWP.????????.IP" then nothing matched the expression.

The way general expressions work in the shell is if there are file matches those that match are returned, else the expression.

Can you do "ls -l" for us to see what you are seeing?

It might be a case sensitivity type thing, note, windows file systems are case-insensitive, UNIX ones are normally case-sensitive.

You might need to try "awp.????????.ip" or some variation.
