schnapps rlist
is the same as schnapps list
in that it takes no mandatory arguments by default, and optional arguments for changing the listing output format (https://gitlab.nic.cz/turris/schnapps/-/blob/master/schnapps.sh#L86-94). However, recent changes in 5991c096 adjusted the argument check for rlist
to only work if exactly 1 arg is provided.
This MR adopts the same argument check for list
, erroring if more than 1 argument is provided, allowing schnapps rlist
to work without arguments.
