I don't know about Sublime Text in particular, but in general, it is bad form to run an editor as the superuser; it will either use the settings of the superuser (okay, but you probably want your customizations) or it will put the files in your home directory, not owned by you (so if you ever want to use your editor as yourself again, you might not be able to change any preferences).
Typically, if you need to edit a file that only root
can write to, you should be using sudoedit
, which will copy the file to a file you can edit, run the editor as yourself, and then copy the changes back. And if you need to edit a file that you don't need to be the superuser to write to, even sudoedit
is not necessary: just run the editor directly!
Addendum
This is a general principle: only run with the permissions strictly necessary. Judging from your other question, you've been running lots of things with sudo
and friends. That's not a good habit to get into: the more things you use sudo
with, the more things become owned by root
and therefore require you to use sudo
again. A vicious cycle. To set things straight again, you may want to set yourself as the owner:
sudo chown -R `whoami` path/to/directory
While you might not want to do this on system files, almost everything in your home directory should be owned by you. When the permissions are right, you should find you almost never have to use sudo
.
