Drop the F option. Probably not supported by the version of egrep.

-F does not work with egrep.
egrep is like grep -E and grep -F is like fgrep - that explains the error message.
-F (plain strings) and -E (extended regular expression) are mutually exclusive.

Try to use grep -E instead of egrep.
Try to use grep -F instead of fgrep.
Both, egrep and fgrep are deprecated.

grep uses regular expressions. * does not mean wildcard, * means 'zero or more of the previous character'.
