Is this a binary or text file? And what are you trying to exactly?

For grep, you would have to put in the character representation of
0xfe since it matches strings.

You could use od -x or hexdump to turn it into hex and then | egrep "
fe|fe |fe$".  This would give you the offsets.

You could also do it programatically.  Perl would probably be the easiest.
