And not:
for name [ in word1 word2 ... wordn ] ; do list ; done
yet it works as expected, or in a way to make it useful.
I have no old "authoritative" sh at hand, but a Solaris 2.7 /bin/sh
spits a dummy on an empty item list. I view that as a dumb design (one
would have to enclose for loops in a check for empty item lists), since
corrected.
Agreed that anything wanting to be portable should take this sort of
thing into account. I'd hate to be the one to sort out all the cr*p
shells. Every other sane programming language allows empty loops.
