Using `ls' Switches Instead of Omit Mode

Question

As per this page

An alternative to using Omit mode: Use C-u s to change the ls switches and immediately refresh. (C-u s refreshes also, so there is very little typing involved.) You can remove -a from the switches to hide dot files, or add -B to hide files ending with ~.

I entered C-u s and then I entered -al -B but this did not eliminate the files ending with ~. What am I doing wrong?

Answer 1

I don't see that. For me switches -al -B (or -alB) remove ~-suffixed file names.

Do you see it if you start Emacs with emacs -Q (no init file)?

• If not then bisect your init file to find the culprit.

• If yes, then what you see might depend on your ls. (I'm on MS Windows, so my Emacs uses ls-lisp.el.)
