TEE CLC - Output completed marker

[sebasmonia]

I'm using the CLI tool of TEE to connect from Emacs and run commands.

I can give the tool commands using stdin using "tf @", the problem is for some commands (example: print) you can't easily tell from the output when it's "done".

Would it be possible to add some sort of marker to be ale to tell when the command completed?

Is -exitcode supposed to be used as the output marker? By matching "ExitCode: " in the output?
