By the way, fgrep will become confused if $FROM starts with a
hyphen.
No, it's not seen as a command line argument, but read from standard
input (unless FGREP is set to "xargs fgrep" :-)); no problem with
leading hyphens there.
What version of fgrep are you using? Modern fgrep implies the `-f'
already -- unless I've misunderstood something about your syntax.
I think you have: he's not telling fgrep to look for the pattern $FROM
in the file $HOME/.procmail/spam, but the other way around (with the
same result): standard input (as provided by echo) is checked for all
patterns in the file (hence -f). Your method
* ? $FGREP -qsix -e "$FROM" some/file
is more elegant, though. (And *there* you need the -e to deal with
leading hyphens.)
