The basic syntax of the ‘cut’ command is as follows:

Here, OPTION can be any of the command options available for ‘cut’, and FILE refers to the file from which you want to cut sections. If no file is specified, ‘cut’ will read from the standard input.

This command will output ‘Hello’, as it cuts the first five bytes of the input.

Example 2: Cutting by Delimiter
