Actually, how about trying it too?  On my system, and therefore
probably on most BSD systems, -i works only for fgrep and grep, not
egrep, which is easily the most useful of the three (fastest, accepts
the most general expressions, etc).  Yes, even for fixed strings, in my
experience egrep is much faster than fgrep (and grep).  I will probably
write something for VAXen using the matchc instruction, so the
(presumably tuned) microcode does the searching.  If I do and it turns
out to be usefully fast, I will probably submit it for consideration
for mod.sources.
