There are only three forms to the Imperative Mood.
It depends who you are adressing your command to :
If it is someone you say 'tu' to , it will be the singular.
e.g. N'écoute pas , Ne cours pas, Ne répond pas ...
If it is someone you say 'vous' to, or several people, it will be vous form.
e.g. N'écoutez pas!, Ne courez pas! Ne répondez pas! ...
( Don't listen, Don't run! Don't answer!)
The final form is the 'nous' if you are yourself included in the command, as in 'allons-y! '(Let's go!)
e.g. Ne courons pas! (Let's not run!) etc..
Hope this answers your question...
