Linux Files

In Linux system, everything is a file and if it is not a file, it is a process. A file doesn’t include only text files, images and compiled programs but also include partitions, hardware device drivers and directories. Linux consider everything as as file.

Files are always case sensitive. Let’s understand it through an example.

In above example, we have two files named as ‘Demo.txt’ and ‘demo.txt’. Although, they both share the same name but still they are two different files.
