As I don't believe there's a way to display that in clish, hitting the tab button at a prompt is probably the easiest thing to do.
clish only shows you the commands you have access to as the current logged in user.
For a user with monitorRole, it should be something like:
add - Add operation.
clear - clear the screen
commit - End transaction by committing changes.
delete - Delete operation.
exit - Exit from shell.
get - Sorry, no help available here.
help - Global help page.
history - Show command history.
load - Load operation.
lock - Enable exclusive access.
quit - Exit from shell.
rollback - End transaction by discarding changes.
save - Save operation.
set - Set operation.
show - Show operation.
start - Start operation.
unlock - Disable exclusive access.
ver - Display system versions
For an adminRole user, you will see a lot more commands.
