Accessing the CLI online help

The CLI online help is context sensitive. Enter a question mark at any prompt or in any position of a command to display all available options.

To access the CLI online help, use one of the following methods:

• Enter a question mark at a view prompt to display the first keyword of every command available in the view. For example:

  <Sysname> ?
  User view commands:
  archive             Archive configuration                                     
    arp                 Address Resolution Protocol (ARP) module                  
    backup              Backup operation
  ...
  

• Enter a space and a question mark after a command keyword to display all available keywords and arguments.

  • If the question mark is in the place of a keyword, the CLI displays all possible keywords, each with a brief description. For example:

    <Sysname> terminal ?
      debugging  Enable to display debugging logs on the current terminal
      logging    Display logs on the current terminal
      monitor    Enable to display logs on the current terminal
    

  • If the question mark is in the place of an argument, the CLI displays the description for the argument. For example:

    <Sysname> system-view
    [Sysname] interface vlan-interface ?
      <1-4094>  Vlan-interface interface number
    [Sysname] interface vlan-interface 1 ?
      <cr>
    [Sysname] interface vlan-interface 1
    

    <1-4094> is the value range for the argument. <cr> indicates that the command is complete and you can press Enter to execute the command.

• Enter an incomplete keyword string followed by a question mark to display all keywords starting with that string. The CLI also displays the descriptions for the keywords. For example:

  <Sysname> f?
    fdisk    Partition a storage medium
    fixdisk   Check and repair a storage medium
    format    Format a storage medium
    free      Release a line
    ftp       Open an FTP connection
  <Sysname> display ftp?
    ftp         FTP module
    ftp-server  FTP server information
    ftp-user    FTP user information
