That's because of that pesky "+" character, which means "one or more occurrence" and is an extended regex and hence supported by egrep (extended grep). Check the man page for egrep in your system.

The equivalent regex for this in grep would be:

Code:
$
$ echo "AAAAAP" | grep '^[A-Z][A-Z]*P'
AAAAAP
$
