As you are probably already aware, everything is considered to be a file in Linux. That includes hardware devices, processes, directories, regular files, sockets, links, and so on. Generally, the file system is divided into data blocks and inodes. With that being said, you can think about inodes as a basis of the Linux file system. To explain it more clearly, an Inode is a data structure that stores metadata about every single file on your computer system.

What is Umask?

Umask, or the user file-creation mode, is a Linux command that is used to assign the default file permission sets for newly created folders and files. The term mask references the grouping of the permission bits, each of which defines how its corresponding permission is set for newly created files. The bits in the mask may be changed by invoking the umask command.

What Are Linux File Permissions?

Setuid, Setgid and Sticky Bits are special types of Unix/Linux file permission sets that permit certain users to run specific programs with elevated privileges. Ultimately the permissions that are set on a file determine what users can read, write or execute the file. Linux provides more advanced file permissions that allow you to do more specific things with a file, or directory.  Typically, these file permissions are used to allow a user to do certain tasks with elevated privileges (allow them to do things they normally are not permitted to do). This is accomplished with three distinct permission settings.  They are setuid, setgid, and the sticky bit.
