Entering Commands and Getting Help
Enter commands, options, and arguments at the CLI prompt. A command name must be typed, but the included command-completion and help features contribute to the command entry process.
To display a list of commands used within a command mode, enter a question mark (?), or use the tab key, or type help at the command prompt. This context-sensitive help feature displays the keywords and arguments for each command. Use complete commands and display keywords and arguments for each command using the tab key to assist with context-sensitive command help and completion.
Table 1 lists the command entered to get help specific to a command, keyword, or argument.
Table 1: Getting Help
Displays a list of commands that begin with a specific character string. Do not leave a space between the string and question mark.
abbreviated-command-entry <tab>
Completes a partial command name.
Lists all commands.
command ?
Lists all keywords for the command. Leave a space between the command and the question mark.
command keyword ?
Lists all arguments for the keyword. Leave a space between the command and the question mark.
Where a text string is used, such as name-string, the following characters are allowed as part of the text string: a-z, A-Z, 0-9, _ (underscore), . (period), , (comma), : (colon), and - (dash).
Informational Note: If you enter an invalid command, then using the ? and tab key have no effect and do not return any changes to the CLI.
Informational Note: The CLI contains an editing ability similar to UNIX and Linux functionality using emacs keys. For example, ^p steps backward through previous commands, ^n moves to the next command in the history, ^a moves to the first character in the command and ^e moves to the end of the line, ^u erases the current line, and ^w erases the previous word.
Informational Note: Also, use the up and down arrows on your keyboard to retrieve the last command entered at the CLI.
