Explanation:
Detailed explanation-1: -Unix allows three forms of access to any file: read, write, and execute. For an ordinary file, if you have read (r) permission, you can use that file as input to any command/program. If you have write (w) permission, you can make changes to that file.
Detailed explanation-2: -There are three basic permissions in each set: read, write, and execute. For files, those are pretty straightforward: “read” lets you see the file’s contents; “write” lets you change the file’s contents; and “execute” lets you run the file as a program.
