-h - show help message
-l - list all selectable input sources
-V - print version number

If no arguments are specified, it prints the current input source.
If <input-source-id> is specified, it selects the specified input source.

Caveats

There is an old bug in macOS related to handling input sources for CJK languages. If you're using the default APIs, when switching languages from the command line (i.e., without creating a GUI application), the switch won't work correctly for languages with composite input (like Japanese and Chinese). @laishulu has implemented a workaround for this issue in his implementation of a similar utility, available at https://github.com/laishulu/macism. If this issue affects you, it's worth checking out his project.
