File Access Privileges

• In Linux, 3 types of access permissions or privileges can be associated with a file

• read (r) grants rights to read a file
• write (w) grants rights to create, write to, or remove a file
• execute (x) grants rights to run the file (to execute the file as a command)

• All 3 permissions can then be applied to each of 3 types of file users

• User owner/creator of the file
• Group group to which user must belong to gain associated rights
• Others Anyone else not User or not a part of Group (we used to call it Rest-of-world)
