About the operating environment: tar behaves as if it is dependent on the operating environment, such as the configuration of the following environments

　　　　　　

Simple_backup_suffix
Backup prefix to use when extracting, if--suffix are not specified. The backup suffix defaults to ' ~ ' if neither is
Specified.

Tar_options
Options to prepend to those specified on the command line, separated by whitespace. Embedded backslashes May used
To escape whitespace or backslashes within an option.

TAPE Device or file to use for the archive if--file are not specified. IF This environment variable are unset, use stdin or
StdOut instead.

tar_longlink_100

The tar feature is very powerful, so we can use it to understand these features, which is commonly used

-C: Create an archive
-X: Expand Archive
-T: Directly view archived files without expanding
-Z: Using gzip compression
-J: Using bz2 compression
-J: Using XZ compression

Small examples of use:

Tar-czf script.tar.gz Script

TAR-XF script.tar.gz
