Typing a command followed by a slash and question mark may display help information about that command's usage.
False
True
True. Typing a command followed by a slash and question mark (e.g., command /?) often displays help information about the command's usage in many command-line interfaces, such as the Windows Command Prompt. This typically shows the syntax, options, and examples for the command.
Other examples of getting help output from command line tools are:
--help or -h: Adding --help or -h after a command often shows information about how to use it. Example: command --help.
help: Typing help with a command name can show instructions. Example: help command.
/help or /?: On some systems (like Windows), using /help or /? gives help. Example: command /?.
No Arguments: Just typing the command by itself might show how to use it. Example: command.
man: On Linux and macOS, the man command shows a detailed manual for a command. Example: man command.
Which pattern is used depends entirely on the Operating System and the Command Line tool being used. It is good to know all the possible options!
