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.

The Esc, y key sequence does not function unless the Ctrl-Y key combination is pressed first. If the
Note
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.

Displaying Persistent CLI History

The Cisco IOS XR maintains the history buffer of CLI commands persistently across user sessions,
router switchover, and router reloads. This buffer not only provides a log of commands entered by
various users, but also lets you trace the activity of active users if the threshold limit of CPU usage is
exceeded. This command is useful for troubleshooting purposes.
To display the history of events corresponding to the CLI session open events, enter the show cli history
brief location command at the EXEC mode as follows:
RP/0//CPU0:router# show cli history brief location 0/RP0/CPU0
No.
