Example: tar cf a / etc, etc. (suffixes in Linux are basically useless, just for administrators)

And you have to add a file name after f, or you can't pack it.

Tar supports three different compression methods:

Gzip: the fastest compression speed, the longest history, and the most widely used

Bzip2: compressed files are not as useful as gzip.

Xz: the latest way to provide the best compression ratio

All three situations can be encountered in the real world, so you have your own options for creating archived files in different formats.

Z for gzip compression: tar zcf compressed file name compressed file name

J for bzip2 compression: tar jcf as above

J for xz compression: tar Jcf as above

Extract the file

The name of the file to be extracted by tar xf
