SubtitleEdit CLI output to stderr(or exit code)

[Hlsgs]

I am unaware of standardized method to determine if SubtitleEdit CLI was successful. Right now, I'm regex-ing through it's console output to determine how many files were converted(I only do one file at a time, not entire folders; so "0 file(s) converted" means error and "1 file(s) converted" means success).

Seeing as SE is not a really a CLI, as you've mentioned here, I presume that it can't emit a proper exit code, but, it should be able to output to stderr, which would prompt Powershell to populate it's $? automatic variable:

In the case of calling an external program, if any information output is passed to stderr then PowerShell will set $? to $false.

What I'm doing works, but it's dependant on SE's console output, which you may choose to alter at some point. Whereas outputting to stderr would be robust.

Thank you!
