@b0rk @endrift only if there’s a way to capture the use of the file handle and set up what amounts to an open-on-use mechanism. I think someone in another branch of the thread mentioned a hypothetical virtual file handle that would work similarly

  @ShadSterling @b0rk @endrift Definitely possible, open an anonymous pipe for the command running under sudo to feed, then open the output file after. The "sponge" command (part of moreutils) does something like this to allow rewriting files, e.g. sort file | sponge file.
  That said, it is much simpler to just open the file and pass the descriptor.

  @endrift hmm do you think it would be possible for the shell to open the file *after* the program starts?
