What is the "ls" directory in my home directory? I was just exploring the directory structure on my Mac and there's a directory in my root/home directory, named ls.

[~]$ ls -l .
.
.
drwxr-xr-x   6 XXXX  staff       192 Dec  8  2018 ls


[~/ls]$ pwd
/Users/XXXX/ls


Could someone help me understand what this directory holds and why is in the  root?

The ls command should reference the /bin/ls command, I'm guessing. Anyone have any ideas?
That ls/ directory is not standard on Mac, so its something you or another user on the Mac have created (either directly, or indirectly by being created by some third party program).

It hasn't got anything to do with the ls command. However, it could reasonably have been made by someone in the middle of a mkdir command thinking that they should just list the directory first - and then erraneously running mkdir ls.

By the way - the directory /Users/xxxx is not called the root directory, but rather the user's home directory.
