Using The Command History Feature; Command Buffering Rules; Controlling The Cli Output - HP 10500 Series Configuration Manual

Using the command history feature

The system automatically saves commands successfully executed by a login user to the following two
command history buffers:
• Command history buffer for the user line.
Command history buffer for all user lines.

Command buffering rules

The system follows these rules when buffering commands:
If you use incomplete keywords when entering a command, the system buffers the command in the
•
exact form that you use.
If you use an alias when entering a command, the system transforms the alias to the represented
•
command or command keywords before buffering the command.
• If you enter a command in the same format multiple times in succession, the system buffers the
command only once. If you enter a command in different formats multiple times, the system buffers
each command format. For example, display cu and display current-configuration are buffered as
two entries but successive repetitions of display cu create only one entry.
To buffer a new command when a buffer is full, the system deletes the oldest command entry in the
•
buffer.
