tar : tar -zxvf yourfile.tar.gz

     -Z, --compress, --uncompress
      (c mode only) Compress the resulting archive with compress(1).
      In extract or list modes, this option is ignored. Note that,
      unlike other tar implementations, this implementation recognizes
      compress compression automatically when reading archives.

     -x      Extract to disk from the archive. If a file with the same name
      appears more than once in the archive, each copy will be
      extracted, with later copies overwriting (replacing) earlier
      copies.  The long option form is --extract.
