The correct saying is on command on demand is incorrect
Command
I do not think that the sentence is grammatically correct. The sentence seems ambiguous to me. Is the statement suggesting that "she has good command" of a group of people or animals? Or, is the statement suppose to imply that "she has command" of the English language?
That is the correct spelling of the word behest (command or request).
Not by itself it isn't. If it had a helping verb (like is or another form of the verb to be), it would be part of a verb. For example, we could say something like this: James is farting his life away. In such a sentence, the verb is "is farting." When the word farting stands alone, it is what we call a verbal, a word made from a verb but functioning as some other part of speech. It might be a gerund, a verbal functioning as a noun, or it might be a present participle, a verbal functioning as an adjective. Here is an example of farting as a gerund, in this case a noun serving as the subject of the sentence: Farting is such fun that I just cannot resist it. Here is an example of farting used as a present participle: Let farting dogs lie. In this sentence farting describes the noun dog and serves as an adjective.

Positive command: "come", negative command: "no comas".
That is the correct spelling of "commander" (capitalized as a rank before a name).
You could use demand or boss.
