A byte is a unit used by most of the computers to represent a character such as a letter, number or typographic symbol. Each byte can hold a string of bits that need to be used in a larger unit for application purposes. The option ‘-k‘ (e.g. –block-size=1K) can be used for displaying all the file system information and usage in 1024-byte blocks. The following command is used to display the information of file system in bytes using the Linux command.
Command:
