I've been using Tramp mode on my Emacs to edit files remotely. I'm also using ido mode. When I add a new file in the same directory of a file I opened using Tramp, I couldn't get Tramp to find the new file(with C-x C-f). Is there a way to refresh Tramp?

        Your question is about ido-mode used with tramp.  To refresh ido auto-complete while in the process of finding a file, you can press C-l, to execute:  ido-reread-directory.

                    1Worked for me once, but not any more. No Idea why. Says: `Symbol's value as variable is void: ido-cur-item`. Any solutions? – reza.safiyat Jan 18 '16 at 15:07

                    2@reza.safiyat that is because you need to call it within the context of opening a file or a directory. To try this, using `ido-find-file` go to a directory you want to refresh and hit "C-l" (within the ido buffer). It will refresh the directory you are currently looking at. – Shlomi Feb 23 '16 at 20:12

                    Funny: for me, I just went to directory I would like to refresh with `C-f` then I just press `C-l` and it have refreshed. – Felipe Sep 10 '19 at 00:24

            As documented here, you can press g in the dired buffer to run revert-buffer and refresh the directory listing.

                    `g` is the usual 'refresh the buffer contents' binding, and works in lots of Emacs modes. – phils Jul 22 '14 at 23:00
