Using octal method,type the exact command you would use to make test.txt have the following permissions dr-xr-x---

That trap question assumes that you cannot have a directory named `test.txt`. That assumption is false. — , Oct 05 '18 at 22:52

A directory named test.txt is OK, but d for a file is not possible. read man chmod — 炸鱼薯条德里克, Oct 05 '18 at 23:55

If test.txt is a text-file, you cannot do this. If it happens be be a directory:

chmod 550 test.txt

Normally I skip orders that are not questions; but in this case here is exactly what you ordered, using the octal method to type out to a TTY the exact command that I would use.

$ printf '\151\156\163\164\141\154\154\040\055\144\040\055\155\040\060\065\065\060\040\164\145\163\164\056\164\170\164\012'

The point where you understand this by yourself, with no further explanation, is the point where Unix shell scripting is becoming second nature. ☺
