It's permitted to put multiple /'s between components in a path name (and something I tend to do since file completion adds then to the end of directories and I'm not yet used to that). Cd, with "..", however, get's confused by this. $ cd /usr/local//src $ pwd /usr/local/src $ cd ../.. $ pwd /usr/local
