Linux tar usage introduction
First, we need to understand two concepts: packaging and compression.

Why should we distinguish these two concepts? This is due to the fact that many compression programs in Linux can only compress one file, so when you want to compress a large number of files, you have to first package the large number of files into a package (tar command), and then use Compression program (gzipbzip2 command). Syntax tar (option) (parameter) option -A or --catenate: add files to the existing backup file; -B: set the block size; -c or --create: create a new backup file; -C: this
