And for completeness' sake,
-V
--version
should print to stdout, ideally a single line like so:
$ python -V # beautifly simple
Python 3.10.4
$ aerc -V # built from master
aerc 0.9.0-11-g037676f
$ zsh --version # maybe some info
zsh 5.8.1 (x86_64-pc-linux-gnu)
$ astronaut -v # small v, oh well
astronaut 0.1.0
Some bad examples:
$ bash --version # bloat!
GNU bash, version 5.1.16(1)-release (x86_64-pc-linux-gnu)
