I really like the emacs terminal but each time I use it to log into my server. I don't know how to use emacs to edit files on the server.

Or it is not possible to do it? I can only edit files on server via ssh edit? However, in the latter case, how can I edit file as root user?

There is Tramp. You can edit a file on another machine using the syntax /ssh:user@machine:/path/to/file. If you take sudo instead of ssh, and empty user and machine, you can edit a local file as root. Like /sudo::/path/to/file.

  • Thanks for your reply. My question is how can I use sudo when I want to edit files on the server. – LifeWorks Mar 31 '16 at 16:22

    Yes, mutihop. /ssh:user@machine|sudo:machine:/path/to/file let you edit files with root credentials on the other machine, after first login as user. – Michael Albinus Mar 31 '16 at 18:50
  • There are several more examples of editing local and remote files as sudo in the tramp help screens in emacs (C-h i and look under Tramp, Multi-hops). Enter them directly as Michael Albinus shows in his response or setup defaults using the link that npostavs provided. – Emacs User Apr 1 '16 at 0:19
