No, since I was using tcsh-6.00 while making those comments, I was
really referring to the `which' built-in. There does not seem to be a
`where' built-in in tcsh-6.00:
Oct 2 (16:38) hal-2000:/tmp
[121]% which echo
echo: shell built-in command.
Oct 2 (16:39) hal-2000:/tmp
[122]% which which
which: shell built-in command.
Oct 2 (16:39) hal-2000:/tmp
[123]% which where
where: Command not found.
Oct 2 (16:39) hal-2000:/tmp
[124]% add sipb
Oct 2 (16:39) hal-2000:/tmp
[125]% which where
/mit/sipb/vaxbin/where
Oct 2 (16:40) hal-2000:/tmp
[126]%
But you're right, there is a builtin `where' in the current Athena tcsh,
and its use in scripts does not produce the same ioctl error that the
built-in which does, so part of my argument for keeping is blown away,
unless you want to use it in a Bourne shell script. The proper defense
for the program would have to come from someone who's actually used it a
lot.
