Correct me if I am wrong
So when you want to give ownership of a file or a folder to a Group you use Chgrp.
Example: Chgrp GroupX /Xfolder : GroupX will have folder ownership of Xfolder
Or Chgrp GroupX /Xfolder/Xfile : GroupX will have only File ownership of Xfile without giving the group GroupX ownership of Xfolder.
Chown , seems like it does the same thing as Chgrp, but it is used to give permission to a user instead of a group
those 4 commands , they looks like they overlap in their usage, that s what confuses me

I read online about each command on :http://www.computerhope.com/unix
but not really enough. the way you explained them, looks good it can be better if you add examples for each command.
usermod - modify a user account
example:
chmod - change file permission / mode bits
example:
chgrp - change group ownership
example:
chown - change file owner and group
example:
Thank you
