Basic CLI commands

The console control commands are the commands that are used for navigating within the CLI and displaying information about the console session. Most of these commands are implemented as global commands. They can be entered at any level in the CLI hierarchy with the exception of the password command, which must be entered at the ROOT level. The console control commands are described in the following table.

Table: Console control commands

<Ctrl-c>	Aborts the pending command.
<Ctrl-z>	Terminates the pending command line and returns to the ROOT context.
back	Navigates the user to the parent context.
clear	Clears statistics for a specified entity or clears and resets the entity.
echo	Echos the text that is typed in. Primary use is to display messages to the screen within an `exec` file.

exit	Returns the user to the previous higher context.

help ?	Displays help in the CLI.

password	Changes the user CLI login password. The password can only be changed at the ROOT level.
ping	Verifies the reachability of a remote host.
pwc	Displays the present or previous working context of the CLI session.
sleep	Causes the console session to pause operation (sleep) for one second or for the specified number of seconds. Primary use is to introduce a pause within the execution of an `exec` file.
ssh	Opens a secure shell connection to a host.
telnet	Telnet to a host.
traceroute	Determines the route to a destination address.
tree	Displays a list of all commands at the current level and all sublevels.
write	Sends a console message to a specific user or to all users with active console sessions.

The list of all system global commands is displayed by entering help globals in the CLI. For example:
