For the cd command, POSIX 2008 requires that after all pathnames in CDPATH have been tested and failed in step 5, then step 6 interprets the directory argument relative to PWD. In other words, this demonstrates a bug:
$ dash -c 'cd /tmp; mkdir -p foo; CDPATH=oops; cd foo; echo $?; pwd' cd: 1: can't cd to foo 2 /tmp while bash gets it correct: $ bash -c 'cd /tmp; mkdir -p foo; CDPATH=oops; cd foo; echo $?; pwd' 0 /tmp/foo Furthermore, POSIX requires that if the element in CDPATH ends in slash, that no additional slashes are added while forming the candidate curpath. In light of the fact that //home need not be the same directory as /home (and indeed, on cygwin, they are distinct entities), this is also a bug: $ dash -c 'CDPATH=/; cd home' //home $ bash -c 'CDPATH=/; cd home' /home -- Eric Blake -- To unsubscribe from this list: send the line "unsubscribe dash" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
