RE: CDPATH bug

[Valkanas Nikos]

You are right. I am starting to think that /bin/sh implementation is
correct and bash implementation is too permissive. If I set CDPATH:

export CDPATH=".:~/work:~/work/HOL"

everything will work correctly with all shells, and be much more
analogous to PATH. However, the analogy to PATH should not be exact.
PATH will not work with an empty PATH, whereas cd should work with empty
CDPATH. Maybe bash should be aligned to the other shells (i.e. no cd to
a subdir unless "." is part of CDPATH, or CDPATH is not set)

Chet Ramey listed some in his mail, I've tried:

ash,  ksh93 and pdksh when invoked with the name "sh", /bin/sh and
/usr/xpg4/bin/sh under sunOS 5.8

They all behave like bash when started with the name "sh"

CDPATH is documented in sh, so there is no reason not to use it,  but
so far the only "sh"  I found that cd to a subdir in the current path
when CDPATH is set  is  zsh when started with the name "sh".
