Hello!

/bin/ls in Mac OS X 10.6.8 (and maybe more releases) does not understand "--dired", only "-dired". Is there a way to make dired use "-dired" instead of "--dired"? (Besides using gls from GNU Coreutils.)

You need to set 'dired-listing-switches'.

The use of "--dired" is hard-coded in `dired-insert-directory'.

Dired checks if ls supports --dired.  In Peter's case, it'll determine
that it's not supported.  So adding "-dired" to `dired-listing-switches'
should in fact do the job.

Bye,

Dear Tassilo,
dear Ellen,
dear Peter,

I am afraid that adding "-dired" to dired-listing-switches did not solve the problem, at least not for current versions of Aquamacs 3 (it looks like an Emacs 24 Mac-specific problem). However, 

(setq dired-use-ls-dired nil)

does (error message gone). There is a caveat about "unusual" file names (e.g. those with leading spaces) in the documentation of dired-use-ls-dired, so maybe this solution is not for everybody.

Warm regards,
Stefan

Indeed, elder Emacsen, versions 23.x, do understand a settings like

	(setq dired-listing-switches "-ahlw -dired")

in the site init file and obey it, i.e., they can work with /bin/ls. All the GNU Emacs 24.x versions fail to obey. In earlier version it was also possible to set

	(setq insert-directory-program "gls" dired-use-ls-dired t)

This looks like being worth a bug report.

Using the above setting is really bad: no directory listing possible when some directory in the absolute path contains a SPACE…

When you can install gls from the GNU Coreutils the settings

	(setq ls-lisp-use-insert-directory-program t)
	(setq insert-directory-program "gls")

allow GNU Emacs 24.1 to use gls.

A second problem exists with possible use of the variable dired-listing-switches. With GNU gls I use "-ahlN" which has to be with the system's ls "-ahlw".
