Recalling Previously Entered Commands

The Cisco IOS XR software records the ten most recent commands issued from the command line in its history buffer. This feature is particularly useful for recalling long or complex commands or entries, including access lists.

To recall commands from the history buffer, use one of the commands or key combinations listed in Table 6-6.

Table 6-6	Command History
Command or Key Combination		Purpose
Ctrl-P or the up arrow key		Recalls commands in the history buffer, beginning with the most recent
		command. Repeat the key sequence to recall successively older commands.
Ctrl-N or the down arrow key		Returns to more recent commands in the history buffer after recalling
		commands with Ctrl-P or the up arrow key. Repeat the key sequence to recall
		successively more recent commands.

Recalling Deleted Entries

The Cisco IOS XR CLI also stores deleted commands or keywords in a history buffer. The buffer stores the last ten items that have been deleted using Ctrl-K, Ctrl-U, or Ctrl-X. Individual characters deleted using Backspace or Ctrl-D are not stored.

Table 6-7identifies the keystroke combinations used to recall deleted entries to the command line.

Table 6-7	Keystroke Combinations to Recall Deleted Entries
Command or Key Combination		Recalls the
Ctrl-Y		Most recent entry in the buffer (press the keys simultaneously).
Esc, Y		Previous entry in the history buffer (press the keys sequentially).

Note The Esc, Y key sequence does not function unless the Ctrl-Y key combination is pressed first. If the Esc, Y is pressed more than ten times, the history cycles back to the most recent entry in the buffer.

Redisplaying the Command Line

If the system sends a message to the screen while a command is being entered, the current command line entry can be redisplayed using the Ctrl-L or Ctrl-R key combination.
