Command Completion
If you terminate input with a Tab key, the CLI will print the remaining
characters of a partial keyword up to the point of ambiguity. In the
“logging history” example, typing log followed by a tab will result in
printing the command up to “logging.”
Getting Help on Commands
You can display a brief description of the help system by entering the help
command. You can also display command syntax by using the “?”
character to list keywords or parameters.
