According to Eric Blake on 7/14/2009 3:39 PM: > 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.
