TAR 命令

Creating an archive using tar command(建立壓縮文件)

Create linux tar gz (Gzip) archive :

tar -czvf myarchive.tgz mydirectory/

tar -czvf myarchive.tar.gz mydirectory/

We use the -t option to create an linux tar archive

• c – Creates a new .tar archive file.
• v – Verbosely(囉嗦地) show the .tar file progress.
• f – File name type of the archive file.
• To create a compressed gzip archive file we use the option as z.

Note:that .tgz is the same thing as .tar.gz.

Create linux tar.bz2 archive

tar -cvfj myarchive.tar.bz2 mydirectory/

tar -cvfj myarchive.tb2 mydirectory/

Note:To create highly compressed tar file we use option as j(filter the archive through bzip2).

Note: tar.bz2 and tbz is similar as tb2
