I want to export the output of vi command :set fileencoding to another file. It seems vi's file encoding detection is better than file command.

How to do that?

I could write a macro with:

:set fileencoding

but this won't export the output.

In vim, you can use redir command. In command mode:

:redir > vim.output | set fileencoding | redir END

Then output of set fileencoding will be save to vim.output. There is many other options of redir, you can see :help redir for more details.

This works in vim, not in vi.
