In a bash, is there a way to combine autocd and CDPATH, that is, to go to a subdirectory of a CDPATH element without typing cd before the dir name?

For example, if i have these directories:

  • ~
  • ~/Leute
  • ~/Leute/Hinz
  • ~/Leute/Kunz
  • ~/Dinge
  • ~/Dinge/Haus
  • ~/Dinge/Auto

and do

~$ shopt -s autocd
~$ export CDPATH=":~/Leute:~/Dinge"

then i can do

~$ Leute

and end up in the ~/Leute directory (that is the autocd thing)


and i can do

~/Leute$ cd Auto

and end up in ~/Dinge/Auto (the CDPATH thing)


but combining the two seems not to work. For example starting in ~/Leute i can’t jump to ~/Dinge/Auto without an explicit cd:

~/Leute$ Auto
bash: Auto: Command not found...

Is there a reason for this? Or is there something else needed to make this work?


Whether by design or oversight, it seems that the test for whether you've typed a directory name doesn't search the CDPATH variable:

execute.cmd.c, function execute_simple_command:

  if (autocd && interactive && words->word && is_dirname (words->word->word))
      words = make_word_list (make_word ("cd"), words);
      xtrace_print_word_list (words, 0);
      goto run_builtin;

The definition of is_dirname is in the same source file:

/* Return 1 if the file found by searching $PATH for PATHNAME, defaulting
   to PATHNAME, is a directory.  Used by the autocd code below. */
static int
is_dirname (pathname)
     char *pathname;
  char *temp;
  int ret;

  temp = search_for_command (pathname, 0);
  ret = (temp ? file_isdir (temp) : file_isdir (pathname));
  free (temp);
  return ret;

From this, it appears that autocd will find directories on PATH, but I tested it with X11 (for /usr/bin/X11/) and got the error X11: No such file or directory.
