Synchronous Information Output
Synchronous information output allows you to continue your operations from where you were stopped
when your input is interrupted.
To enable synchronous information output, use the info-center synchronous command. For more
information about synchronous information output, see Information Center Configuration in the System
Volume.
undo Form of a Command
Adding the keyword undo can form an undo command. Almost every configuration command has an
undo form. undo commands are generally used to restore the system default, disable a function or
remove a configuration. For example, the info-center enable command is used to enable the
information center, while the undo info-center enable command is used to disable the information
center. (By default, the information center is enabled.)
Editing Features
The CLI provides the basic command editing functions and supports multi-line editing. When you execute
a command, the system automatically goes to the next line if the maximum length of the command is
reached. You cannot press Enter to go to the next line; otherwise, the system automatically executes the
command. The maximum length of each command is 510 characters.
Table 5 lists these functions.

Displays history commands
Tab
Pressing Tab after entering part of a keyword enables the fuzzy help
function.
• If finding a unique match, the system substitutes the complete
keyword for the incomplete one and displays it in the next line.
• When there are several matches, if you repeatedly press Tab, all
the keywords starting with the letter that you enter are displayed in
cycles.
• If there is no match at all, the system does not modify the incomplete
keyword and displays it again in the next line.
NOTE:
When editing the command line, use other shortcut keys (For details, see Table 2 ) besides the shortcut keys
defined in Table 5 , or define shortcut keys by yourself. (For details, see Configuring CLI Hotkeys .)
