In Linux, the basic unit of file size is the byte. A byte is a unit of digital information that consists of 8 bits. It is the smallest unit of storage on a computer and is used to represent individual characters or symbols in a text file. However, when dealing with larger amounts of...

It’s often helpful to view file sizes in a way that’s easy to understand, rather than just a raw number of bytes. This is what we call a “human-readable” format. To display file sizes in common units like Kilobytes (KB), Megabytes (MB), or Gigabytes (GB), when using the `ls...
