There is often confusion between these terms when studying Spanish grammar: command, imperative and present subjunctive.
A command in Spanish
A command in Spanish is simply "an order" given to a person. An order (or sometimes just a suggestion) can be given in different ways in Spanish. One of these ways is by using the imperative forms. You can express a command in an affirmative way (e.g. "Go!") or a negative way, (e.g. "Don't go!"). Depending on whether it is affirmative or negative and also depending on who the order/suggestion is addressed to, we use different forms of the imperative.
The imperative in Spanish
The imperative in Spanish is a mood. The imperative forms or conjugations must be studied by subject pronoun, as each different subject pronoun follows a different rule for their conjugations/endings. It is also important to note that the imperative conjugations are different for affirmative commands and negative commands.
Here are all the imperative conjugations:
Imperative of tú for most verbs (affirmative commands)
Imperative of tú for all irregular verbs (irregular affirmative commands)
Imperative of vosotros for all verbs (affirmative commands)
Imperative of tú / vosotros/vosotras (negative commands)
Imperative for usted/ustedes / nosotros/nosotras (affirmative and negative commands)
Present Subjunctive conjugations in Spanish used for commands
