'\0'or'0') - Hardlink (typeflag:
'1') - Symlink (typeflag:
'2') - Directory (typeflag:
'5') - PAX data (typeflag:
'x') (mtime, path, linkpath, uid, gid) - GNU long path name (typeflag:
'L') - GNU long link name (typeflag:
'K')
Other entry type will be extracted as a regular file.

require "tarball"
# Extracts all files in "archive.tar" to under the "data" directory.
Tarball.extract_all("archive.tar", "data")
Tarball.open("archive.tar") do |tar|
# list of included file system objects.
tar.filenames
#=> ["dir/", "dir/file_name.txt", "dir/image.png"]
# extract specific file to specific path.
tar.extract_file("dir/file_name.txt", "other_name.txt")
# write content data to IO object.
tar.write_content("dir/file_name.txt", STDOUT)
end
# open gzipped tar archive
Tarball.open_gz("archive.tar.gz") do |tar|
