The command :sort u starts at position 1.

In the example the artist name starts at position 20, so I'd like to start sorting there.

This is the result I'd like to get

Is this something easily done without plugins or should not attempt that? Google spits out a lot of user defined scripts, but nothing working out of the box...

Answer 1

Out of the box, you can sort starting at a virtual column

:sort /\%20v/

from :help :sort

Answer 2

You can skip the first part of the line (until the "|" char) in your sort by the VIM command:

:sort /^[^|]*/
