Effects of permissions on files

By default, the user name is the user owner and owner group of a file’s contents. In the above examples, the user shobhit was logged in and created the file f_shobhit, so automatically shobhit becomes the user owner and owner group. To discuss the effects of permissions, file f_shobhit is moved to a directory /home/Common such that permissions 777 are implemented on the Common directory. This is done so that all the members of the group and other users can have access to the file.

Let us clear all the permissions from the file (leaving the right side of the permission assignment expression blank will do the trick). Then the step-by-step effects of permissions will be elaborated by assigning one permission at a time.
