Save a file you edited in vim without the needed permissions
:w !sudo tee %
Why is this command so awesome? Peter described it quite well:
This happens to me way too often. I open a system config file in vim and edit it just to find out that I don’t have permissions to save it. This one-liner saves the day. Instead of writing the while to a temporary file :w /tmp/foobar and then moving the temporary file to the right destination mv /tmp/foobar /etc/service.conf, you now just type the one-liner above in vim and it will save the file.
