entered-but-not-submitted
commands.

Understanding command-line error messages

When you press Enter to submit a command, the command line interpreter examines the command
syntax. If the command passes syntax check, the CLI executes the command. If not, the CLI displays an
error message.
Table 4 Common command-line error messages
Error message
% Unrecognized command found at '^' position.
% Incomplete command found at '^' position.
% Ambiguous command found at '^' position.
Too many parameters.
% Wrong parameter found at '^' position.

Using the command history function

The system can automatically save successfully executed commands to the command history buffer for
the current user interface. You can view them and execute them again, or set the maximum number of
commands that can be saved in the command history buffer.
A command is saved to the command history buffer in the exact format as it was entered. For example,
if you enter an incomplete command, the command saved in the command history buffer is also
incomplete. If you enter a command by using a command keyword alias, the command saved in the
command history buffer also uses the alias.
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 in the buffer.
By default, the command history buffer can save up to 10 commands for each user. To set the capacity
of the command history buffer for the current user interface, use the history-command max-size
command.
