Dang, that's smaller than ed(1), 143 kB, itself. ed(1) seems better and better (if EDLIN.COM equivalent is unavailable for Unix). - Anubhav -- ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

After you drop into single user, say the magic words:
# mount -a
that will mount all the filesystems and then vi will be available.

D'ohsorry. Dumb question, but thanks for answering anyway!

Not necessarily a dumb question. What if you can't mount
/usr ? then you've even more trouble. You can learn to
use ed(1), but that's like going back thirty years. Not that
we hate anyone who was using computers back then ...
There was some discussion on the lists (IIRC) a while back
on the idea of building a small editor binary that you like
(trying to remember some of the possibilities: zed, ved, led,
sted, (but not ted), ee (already in the base system), pico, nano,
nah, can't really remember :- ) and cp'ing it to /bin in preparation
for just such an emergency. With root partitions {generally}
being a tad larger these days than in the elder times, it might
be a feasible idea...I'm pretty sure *someone* out there has
tried it. Come to think of it, I may. :-)

There was some discussion ... on the idea of building a small editor binary that you like ... and cp'ing it to /bin in preparation Remember to link your favourite editor statically before even bother to copy. Currently, ee is linked here (4.10-p4) to ... libncurses.so.5 = /usr/lib/libncurses.so.5 (0x28073000) libc.so.4 = /usr/lib/libc.so.4 (0x280b5000) Whatever happens to the editor, it needs to be self contained/sufficient by being small, statically compiled, and be usable w/o the facility of curses.

On i386 platforms, I build a copy of e3vi from ports and cp it to
/root/bin. It's 12.8k (!) and, as long as you don't get too fancy, it's
a reasonable vi clone.
Saved my bacon a few times already.
