Vim – Re-Edit as Root

rootsudovimvimrc

I often open a file in vim, make some changes and when it's time to save the file is read-only.. (owned by another user). I'm looking for tips on how I could re-open the file
as root and keep my changes without first saving it to a temporary file for copy or re-edit
as root.

:w !sudo tee %
I often forget to sudo before editing a file I don't have write permissions on. When I come to save that file and get a permission error, I just issue that vim command in order to save the file without the need to save it to a temp file and then copy it back again.

Yes, this is possible.

In /etc/sudoers the item immediately following the equals is the user that the command will be allowed to execute as.

tom  ALL=(oracle) /bin/chown tom *

The user (tom) can type sudo -u oracle /bin/chown tom /home/oracle/oraclefile

Ssh – How to bring .vimrc around when I SSH

I feel your pain. I have all my ~/.*rc files under version control (Subversion), has worked great since I started in 1998, using CVS. One way to do it, is to check out all your rc files like this when you stand in your home directory:

svn co svn+ssh://user@host/path/to/repo/trunk/home/user .
A    .signature
A    .vimrc
A    .bashrc
A    .screenrc
A    .psqlrc
[...]
Checked out revision 7645.

This way the config files will also be synced and updated across the various computers when you run svn update.
