Automatically read and write files using su or sudo
This package facilitates automatic privilege escalation for file
permissions using TRAMP.
You can install the package by either cloning it yourself, or by
doing M-x package-install RET su RET.
After that, you can enable it by putting the following in your init
file:
(su-mode +1)
When `su-mode' is enabled, you will be able to edit files which you
lack permissions to write. `su-mode' will automatically switch the
visited path to a TRAMP path encoding the correct privelege
escalation just before you save the file. See the README for more
info.
