You need to use the tar command to create an archive (also known as tar ball) under Linux operating systems. The tar command can create and manipulate archive files. It can even extract files from zip, ar, cpio, shar, ISO 9660 cdrom images, pax and other archives.
What is an archive?
An archive is nothing but you bundle (put) many files together into a single file on a single tape or disk. You can restore individual files from the archive on any Unix-like systems.

- -t : Display the contents (file list) of an archive.
