How many files do you have in that directory? The error is that grep is unable to handle the list of files sent in as there are too many of them.

What do you want to do ?

To find files matching the pattern AA*B* (ie. AA123B456) in current directory :
Code:
ls | grep '^AA.*B'

To find files matching regular expression AA*B* (ie (AAAAB) in current directory :
Code:
ls | grep 'AA*B*'

In all cases you must protect the pattern or regular expression with suotes to prevent an interpretation by the shell.

Jean-Pierre.
