That's factually incorrect, which is worse.

Imperative mood: subject you is implied, so no need to write it.

Zero article/bare noun phrase: allows omission of your, the, etc. in fixed instructions.

Standard negation: "don’t" is the grammatical way to negate an imperative.

Sadly that is factually correct and none of the links in your reply actually supports your point.

The rule about the zero article doesn't list the case of a noun after an imperative.

The first link is about the subject, not the object and the third is about negative imperative. Why are you posting links about completely unrelated things?

Once again, using a noun without an article this way is gramaticaly incorrect.

"Share profile photo" would be grammatically incorrect as a complete sentence.

But it's perfectly grammatically correct as a command label.

English has different grammar rules in different contexts. For example, newspaper headlines omit articles all the time. That doesn't make the NYT grammatically incorrect on every page, though. Because they're using correct headline grammar, which is different from sentence grammar.

Heres a secret: Grammer rules are just whats colloquially acceptable speech 50 years ago

[tremon]

That's commonly called Grandma's rules, sometimes shortened to gram's rules. I've never seen the spelling "grammer" before, even though gram'r is arguably more correct than gram's.

Agree to disagree. The reason it sounds robotic is because it's grammaticaly incorrect. The article is not optional before the object in this sentence.

How about these commands:

Raise anchor, fix bayonets, hands up

I think I'm with crazygringo on this one, there's special command grammar.

[Thorrez]

The 2nd and 3rd examples are plural. You don't need an article for plural nouns. "Fix bayonets." and "Fix the bayonet." are standard grammar. "Fix bayonet." isn't.

[card_zero]

Well, hands up is lacking a verb, and fix bayonets is in a funny passive tense - or something - because it seems to say "generally go around looking for bayonets to fix", but means specifically "fix your bayonets". In fact hands up is like that too, the intent is "put your hands up", not just "put hands up" in the abstract.

Then there's informational signs, too. Wet floor is not an instruction. Labels generally aren't sentences.

Or instructions on signs: ring bell for assistance, return tray to counter, close gate after use.
