Getting Help on Commands
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 following a command with the “?” character to list keywords or parameters.
Showing Commands
If you enter a “?” at the command prompt, the system will display the first level of keywords for the current configuration mode (Exec, Global Configuration, or Interface). You can also display a list of valid keywords for a specific command. For example, the command “show ?” displays a list of possible show commands:
RoamAbout 3000#show ?

The command “show interface ?” will display the following information:

<cr>
RoamAbout 3000#show interface
Partial Keyword Lookup
If you terminate a partial keyword with a question mark, alternatives that match the initial letters are provided. (Remember not to leave a space between the command and question mark.) For example “s?” shows all the keywords starting with “s.”
RoamAbout 3000#show s?
snmp sntp station svp system RoamAbout 3000#show s
