This may be a little confusing, but is indeed the defined POSIX behaviour for pwd and cd. $PWD is used to store the "logical" path (potentially containing symlinks) that was cd'ed to. You can avoid the special behaviour with the -P (physical) option. cd -P will not treat symlinks specially and store a pathname not containing symlinks in $PWD; pwd -P will ignore $PWD and show a pathname not containing symlinks. A further thing to note is that csh does not have a pwd builtin (you are supposed to use dirs or prompt substitutions apparently) and that FreeBSD's /bin/pwd has the -P behaviour by default (you need -L to make it use $PWD). -- Jilles Tjoelker _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
