Determination of file lists from selected folders without returning directory names

[SF Markus Elfring]

Hello,

The tool “ls” supports the filtering of directory contents. I am looking for
possibilities for performing such data processing a bit faster when directory
names can (and should) be excluded.

A corresponding result could be achieved by using a subshell (which I would
like to avoid for this use case) for a command like “(cd ${my_dir} && ls *txt)”.

Can such functionality become interesting for any more software tools?

Regards,
Markus
