Description
The tar program is used to store or expand tar archive files. Archive files can be stored on disks or as common files. Tar requires parameters. Optional parameters include a, c, d, R, T, U, and X. You must specify at least one parameter for tar before using tar, you must specify the file or directory to process. If a directory is specified, all subdirectories under the directory will be added to the archive.
Example:
1) Expand abc.tar.gz run the command tar xvzf abc.tar.gz expand abc.tar run the command tar xvf abc.tar
2) Save the man directory and Its subdirectories in the current directory as an archive man.tar CF man.tar./man

Only append newer files to the Archive
-X, -- Extract, -- get
Expand an object from an archive
Other parameters
