Farooq | فاروق<p>So I was short on storage on my archive drive. I saw librewolf source code. It was <code>tar.gz</code> and ~800MB. I uncompressed it then recompressed it with <code>bzip2 -9</code> and now it's ~600MB. Generally <a href="https://cr8r.gg/tags/bzip2" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bzip2</span></a> has better compression for such these data than <a href="https://cr8r.gg/tags/gzip" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>gzip</span></a>.</p><p>Edit: But don't do <code>bzip2 -9</code> all and everywhere. Sometimes <code>-4</code> is the same as <code>-9</code> however the latter being tons slower. Also there is <code>pbzip2</code> for using all your CPU cores. </p><p><a href="https://cr8r.gg/tags/compression" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>compression</span></a> <a href="https://cr8r.gg/tags/compressionalgorithm" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>compressionalgorithm</span></a> <a href="https://cr8r.gg/tags/textcompression" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>textcompression</span></a> <a href="https://cr8r.gg/tags/opensource" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>opensource</span></a> <a href="https://cr8r.gg/tags/tech" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>tech</span></a> <a href="https://cr8r.gg/tags/linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>linux</span></a> <a href="https://cr8r.gg/tags/unix" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>unix</span></a> <a href="https://cr8r.gg/tags/bsd" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>bsd</span></a> <a href="https://cr8r.gg/tags/freebsd" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>freebsd</span></a></p>
