Linux file permissions
- [Instructor] Linux file systems use a permission structure where each file or folder belongs to both an individual user and a group. There are two commands used to change the ownership of files and folders. The "chown" command, short for "change owner" changes the user owner of a file or folder. While the "chgrp" command, short for "change group" changes the group owner. We also use the "chmod" command, short for "change mode" to alter the permissions granted to users or groups on files. Linux uses three different permissions for each file. Read permission, abbreviated with an "r", write permission, abbreviated with a "w" and execute permission abbreviated with an "x". And it also uses letter abbreviations for each type of owner. The user owner, abbreviated with a "u", the group owner, abbreviated with a "g" and all other users abbreviated with an "o". Now one quick exam tip, be careful not to confuse the "User Owner"…
