I sometimes forget whether it is a plural form or a singular form with a terminal command, so I thought it would be easy to know, so I looked it up.
% rails g --help
Will display a list of commands that follow rails g.
It is limited to the gems you have installed, but the commands that can be used with each gem are displayed.
You can also see the delete command by changing g to d.
You can use it when you forget the command!
It ’s a complete digression,
% cal
When you execute, the calendar is displayed.
