bash(1) also has ‘**’ if ‘shopt -s globstar’.

Did you never have a Unix with fine man pages to read?  :-)  Before info(1).
Or ‘The Unix Programming Environment’ mentions sort(1)'s -u on page 106.

‘... **/*.py’ using the ‘**’ Bakul mentions above.

A lot of the time, POSIX find's ‘-exec foo {} +’ suffices and runs
foo with as many arguments as will just fit under argv[]s limits,
like xargs by default and unlike find's one-at-a-time behaviour with
‘-exec foo {} \;’.

Clearly, you're a trendsetter.  :-)  Tiling window managers are popular,
e.g. https://en.wikipedia.org/wiki/I3_(window_manager)
