What I learned:

One essential thing that everyone who is fairly new to Linux heard or read statements such as "in Linux, everything is a File."


While it is true that each and everything is a file, if something is not a file then it must be as process on system. When a file is created or transferred to a system, it occupies some space on the physical disk which is considered to be in a specific format or file type. In the Linux system, files and directories are not differentiate but directories does have an important job, which is to store the other files in a group for easy location. All of the hardware components are represented as files and they system communicates with them using these files.

Different types of files:

• Ordinary Files- Files that contain text, data or program instructions. They are also the most common type of files to find on the linux system which include:

• Readable files

• Binary files

• Image files

• Compressed files

• Special Files- They transfer large blocks of data and information at a specific time.

• Block files- device files that provide buffered access to system hardware components. They are a method of communication with device drivers through the file system.

• Directories- Special files that store both ordinary and other special files. They are organized on the Linux system in a hierarchy which starts from the root directory.
