でないと as in the conditional phrase.

> 例：これをやれ。でないと殺す。

> 例えば、じゃないと？

Never heard of it though. If there is no such thing then is でないと even
considered formal in the first place or just neutral if it doesn't have a
casual/contracted form?

question
colloquial-language contractions copula formality
Is there a contracted/casual form of でないと？
There is the (Kanto) colloquial form 「で **ねえ** と」, but other than that, I
don't think we have what you are looking for.

「じゃないと」 is different since it is the contracted form of 「で **は** ないと」 and not
of 「でないと」.

answer
I think that should be しないと though because you used やる, a verb, in the
previous sentence, so you need to follow up with another verb.
