When using Cygwin, if I type "which perl", and I'm using the bash
shell, I get:

/cygdrive/c/Perl/bin/perl

as my answer. If I switch to zsh and type the same thing ("which
perl"), I get:

/cygdrive/c/Perl/bin//perl

with a double slash in the path. Since the only variable that changed
is the shell, I'm guessing it's the shell's doing, but I'm not sure.

Any idea what that double slash is about?

Thanks.

Check your PATH variable, there's probably
/cygdrive/c/Perl/bin/ in it instead of /cygdrive/c/Perl/bin

which is built in zsh, that may be  why you get a different
result than with /usr/bin/which. (with the /usr/bin/which I have
here, I get a double / also, also with pdksh "type")

I'm using Cygin/bash and do not get symptoms with my zsh 4.0.6.
It might related to what your path is.  I get '/usr/bin/perl'
with bash/which.  Here's my PATH (haven't experienced any probs
with it):

.:/home/tec/bin:/usr/local/bin:/usr/bin:/bin:/cygdrive/c/WINDOWS:/cygdrive/c/WINDOWS/COMMAND

Just to add that, as you probably know, the double slash will be
treated as a single slash in path names, so there is no real need
for concern.
