My homework asked me to find what ls .. does.
I tried to search the internet but I couldn't find any answer to the question.
Does someone know what this command does?

`..` is the parent directory – Clive Feb 21 '19 at 17:23

`.` and `..` have special meaning here, `.` means current directory whereas `..` means one level up. so doing `ls ..` means listing the content of parent directory. You should delete this question. if your quesry is answered. – P.... Feb 21 '19 at 17:23

.. is an entry in the current directory that refers to the parent of the current directory. It's not a special convention used just by ls. For example:
$ cd /usr/bin
$ pwd
/usr/bin
$ cd ..
$ pwd
/usr
$ [ -d .. ] && echo "It's a directory"
It's a directory
$ stat ..
<output specific to your installed version of stat>
