Searching endlessly and not grasping onto a solution. Thanks for your help!

I have a folder that has "drw------- 1 admin admin"
I want "user" to be able to "ls"
I chmod the folder to this "drw----r-x 1 admin admin"
Now "user" can "ls"
So can everyone else.
I only want "user" to be able to see the contents of "folder".
I don't what to change "admin admin" of folder.

How?

Put "user" in the "admin" group. Chmod to be 750 to attain drw-r-x---

Take note of who else is in the "admin" group.

Since "admin" is more general purpose, then consider using an alternate group for ownership of this directory, or adjust the user's in the "admin" group, but cautiously. I don't normally mess with the "admin" group and instead if I have a sub-directory where I wish to control the access per user, I would chown and chgrp to have it be unique versus a system typical choice

You can also use ACLs for a more fine-grained control:

Permission is:

Owner - Group - Others or everyone else

Or try changing the Umask for that folder to 277.

This article gives a good intro to Linux permissions: https://www.linux.com/learn/understa...le-permissions

Note that, as far as Linux is concerned, everything is a file, so the article also applies to directories, even though it says "file" in the title.

Well coached from the master helpers. Problem is solved if OP follows the hints above.

I only wanted to clarify on something from the OP what means he/she in saying:
Do you mean the "user" group... or a particular login $USERNAME ?

If you mean the "user" group then you may need to juggle up properties of two existing groups which may not be favorable.

But if you mean "user" as particular login $USER then the solution is simple:

that particular user login name as "vRanger" becomes now a true scout ranger who should be able to do what the "owner" of the folder/file can.

Hope that helps. Good luck and enjoy.
