• Setting File Permissions in UNIX
  Files and directories in the UNIX File System have a set of "permissions" that determines who is allowed access to them. The permissions are "read" (the ability to read or copy the file or directory), "write" (the ability to edit, delete, or otherwise change the file or directory), and "execute" (the ability to execute a program file or to change into and browse a directory). The level of each of those permissions is assigned to each of 3 different types of people: the owner of the file (e.g. you own the files in your home directory), members of the owner's group (a group can be comprised of any set of users), and the world (everyone else with an account on the computer, not really the whole world).
