Detailed TAR command parameters

Description

The tar program is used to store or expand tar archive files. Archive files can be placed on disk or saved as regular files. Tar requires parameters. The optional parameters are A, c, d, r, t, u, x. You must first specify at least one parameter for tar when using tar; then, you must specify the file or directory to be processed. . If you specify a directory, all subdirectories under that directory will be added to the archive.

Application example:

1)Expand abc.tar.gz Use the command: tar xvzf abc.tar.gz Expand abc.tar Use the command: tar xvf abc.tar

2) Save the man directory and its subdirectories in the current directory as an archive. man.tar tar cf man.tar ./man
