Description
The display history-command command is used to query selectively the history
commands. All the history commands are stored in the history command buffer. When
the history command buffer is full, the oldest information in the buffer will be replaced by
new information.
The number of history commands obtained through the display history-command
command, Command-Number, depends on the size of the history command buffer set
through the history-command max-size command, and Command-Number should
not be bigger than the size of the history command buffer Max-size. If the specified
Command-Number is bigger than the Max-size, all the commands in the history
command buffer will be queried.
