# To extract an uncompressed archive:
tar -xvf /path/to/foo.tar

# To create an uncompressed archive:
tar -cvf /path/to/foo.tar /path/to/foo/

# To extract a .gz archive:
tar -xzvf /path/to/foo.tgz

# To create a .gz archive:
tar -czvf /path/to/foo.tgz /path/to/foo/

# To list the content of an .gz archive:
tar -ztvf /path/to/foo.tgz

# To extract a .bz2 archive:
tar -xjvf /path/to/foo.tgz

# To create a .bz2 archive:
tar -cjvf /path/to/foo.tgz /path/to/foo/

# To list the content of an .bz2 archive:
tar -jtvf /path/to/foo.tgz

# To create a .gz archive and exclude all jpg,gif,... from the tgz
tar czvf /path/to/foo.tgz --exclude=\*.{jpg,gif,png,wmv,flv,tar.gz,zip} /path/to/foo/

# To use parallel (multi-threaded) implementation of compression algorithms:
tar -z ... -> tar -Ipigz ...
tar -j ... -> tar -Ipbzip2 ...
tar -J ... -> tar -Ipixz ...
