Filtering and stderr

[BPJ]

Can I get stderr directed to another file or buffer with `:!` (other than using shell redirects)? I'm sure there is an option but I can't find it! :-)

Regrettably, the short answer is no.

Hello

The ! is the shell escape. It will be using the shell, and redirecting can be done via shell redirects.

You can write a wrapper script that might take a file (or not) that will generate the file you want. In that shell script you might use shell redirects.

Or write/rewrite the utility that you will be using with !. That will create a file using stderr.

If you want to redirect to a buffer you can use the above again. But you might need to write a vim function, command and/or define mappings, based on your requirements.

Regards
