Explanation
The cut command is used to extract selected portions of each line of a file or a stream. The -f option is used to specify the fields to be extracted, separated by commas. The -d option is used to specify the delimiter that separates the fields. The default delimiter is the tab character. The cut command can only select output by field position, not by field content. The cut command can also work on non-ASCII text, such as UTF-8 encoded text. The cut command can use different input and output delimiters, but only if the output delimiter is specified by the --output-delimiter option. The cut command cannot reorder fields, meaning that the output fields will always appear in the same order as the input fields. To reorder fields, other commands such as awk or sed can be used.
