Using the Command-Line Interface in Cisco IOS XE Software
Using the CLI
vi
The following examples show how to use the help commands:
help
Router> help
Help may be requested at any point in a command by entering a question mark '?'. If nothing
matches, the help list will be empty and you must backup until entering a '?' shows the
available options.
Two styles of help are provided:
1. Full help is available when you are ready to enter a command argument (e.g. 'show ?')
and describes each possible argument.
2. Partial help is provided when an abbreviated argument is entered and you want to know
what arguments match the input (e.g. 'show pr?'.)

Understanding Command Syntax
Command syntax is the format in which a command should be entered in the CLI. Commands include
the name of the command, keywords, and arguments. Keywords are alphanumeric strings that are used
literally. Arguments are placeholders for values that a user must supply. Keywords and arguments may
be required or optional.
Specific conventions convey information about syntax and command elements.
Table 3
describes these
conventions.
