Hi-
I wouldn't be surprised if this has already been addressed, but I was
browsing the source for tee in shellutils 2.0 and noticed a FIXME
comment on line 146:
/* FIXME: warn if tee is given no file arguments.
In that case it's just a slow imitation of `cat.' */
So, I think I fixed it. You will find the diff (generated w/ diff -u3)
below. This is the first time I've ever submitted a diff for anything,
so feel free to let me know if I've done anything wrong (or if my code
sucks :).
Thanks,
Nathan Lynch
