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.
