To get help specific to a command mode, a command, a keyword, or an argument, perform one of the following
commands:
Command Purpose
Help
Obtain a brief description of the help system in any command mode.
?
List all commands available for a particular command mode.
When using context-sensitive help, the space (or lack of a space) before the question mark (?) is significant. To
obtain a list of commands that begin with a particular character sequence, type in those characters followed
immediately by the question mark (?). Do not include a space. This form of help is word help, because it completes a
word for you.
To list keywords or arguments, enter a question mark (?) in place of a keyword or argument. Include a space before
the question mark (?). This form of help is command syntax help, because it reminds you which keywords or
arguments are applicable based on the command, keywords, and arguments you already have entered.
Example of Context Sensitive Help
The following example illustrates how the context-sensitive help feature creates an access list from the configuration
mode.
Enter the letters “co” at the system prompt followed by a question mark (?). Do not leave a space between the last
letter and the question mark (?). The system provides the commands that begin with co.
Switch# co?
configuration Enter configuration mode
copy Copy from one file to another
Switch# co
Enter the configure command followed by a space and a question mark (?) to list the command’s keyword(s) and a
brief explanation:
Switch# configuration ?
<cr>
Note that in the example below, if you enter the ip command followed by the Return Key or Enter, the system returns
the prompt that the command is incomplete.
Switch# copy
% Invalid command input
Switch#
