Obtaining Help
Obtain a list of keywords and a brief functional description of those keywords at any CLI mode using the ? or help command:
● To list the keywords available in the current mode, enter ? at the prompt or after a keyword.
● Enter ? after a command prompt to list all of the available keywords. The output of this command is the same as the help
command.
DellEMC#?
bmp BMP commands
cd Change current directory
clear Reset functions
clock Manage the system clock
● Enter ? after a partial keyword lists all of the keywords that begin with the specified letters.
DellEMC(conf)#cl?
class-map
clock
DellEMC(conf)#cl
● Enter [space]? after a keyword lists all of the keywords that can follow the specified keyword.
DellEMC(conf)#clock ?
summer-time Configure summer (daylight savings) time
timezone Configure time zone
DellEMC(conf)#clock
Entering and Editing Commands
Notes for entering commands.
● The CLI is not case-sensitive.
● You can enter partial CLI keywords.
○ Enter the minimum number of letters to uniquely identify a command. For example, you cannot enter cl as a partial
keyword because both the clock and class-map commands begin with the letters “cl.” You can enter clo, however,
as a partial keyword because only one command begins with those three letters.
● The TAB key auto-completes keywords in commands. Enter the minimum number of letters to uniquely identify a command.
● The UP and DOWN arrow keys display previously entered commands (refer to Command History).
● The BACKSPACE and DELETE keys erase the previous letter.
● Key combinations are available to move quickly across the command line. The following table describes these short-cut key
combinations.
