Slackware 13.1 x86_64 stable is released!
Lots of thanks are due -- see the RELEASE_NOTES and the rest of the
ChangeLog for credits. The ISOs are on their way to replication,
a 6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We are taking pre-orders now at store.slackware.com, and offering
a discount if you sign up for a subscription. Consider picking up
a copy to help support the project. Thanks again to the Slackware
community for testing, contributing, and generally holding us to a
high level of quality. :-)
Enjoy!

It uses a different compression algorithm from <tt -class="COMMAND">gzip</tt>, which results in some advantages and some disadvantages. The -main advantage for <tt class="COMMAND">bzip2</tt> is the compressed file size. <tt -class="COMMAND">bzip2</tt> will almost always compress better than <tt -class="COMMAND">gzip</tt>. In some instances, this can result in dramatically smaller -files. This can be a great advantage for people on slower modem connections. Also -remember, when downloading software from a public ftp server, it's generally good -netiquette to download the <tt class="FILENAME">.bz2</tt> files instead of the <tt -class="FILENAME">.gz</tt> files, as this results in less overhead for the generous people -hosting the server.</p> - -<p>The disadvantage to <tt class="COMMAND">bzip2</tt> is that it is more CPU intensive -than <tt class="COMMAND">gzip</tt>. This means that bzipping a file will generally take -longer and will use more of the CPU than gzipping the file would. When considering which -compression program to use, you must weigh this speed vs. compressed size and determine -which is more important.</p> - -<p>The usage of <tt class="COMMAND">bzip2</tt> is nearly identical to <tt -class="COMMAND">gzip</tt>, so not much time will be spent discussing it. Like <tt -class="COMMAND">gunzip</tt>, <tt class="COMMAND">bunzip2</tt> is identical to <tt -class="COMMAND">bzip2 -d</tt>. The primary difference in practical usage is that <tt -class="COMMAND">bzip2</tt> uses the <tt class="FILENAME">.bz2</tt> extension.</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">bzip2 <var -class="REPLACEABLE">filename</var></kbd> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">bunzip2 <var -class="REPLACEABLE">filename.bz2</var></kbd> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">bzip2 -9 <var -class="REPLACEABLE">filename</var></kbd> -</pre> -</td> -</tr> -</table> -</div> - -<div class="NAVFOOTER"> -<hr align="LEFT" width="100%" /> -<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" -cellspacing="0"> -<tr> -<td width="33%" align="left" valign="top"><a href="archive-files.html" -accesskey="P">Prev</a></td> -<td width="34%" align="center" valign="top"><a href="index.html" -accesskey="H">Home</a></td> -<td width="33%" align="right" valign="top"><a href="archive-files-tar.html" -accesskey="N">Next</a></td> -</tr> - -<tr> -<td width="33%" align="left" valign="top">Archive Files</td> -<td width="34%" align="center" valign="top"><a href="archive-files.html" -accesskey="U">Up</a></td> -<td width="33%" align="right" valign="top"><tt class="COMMAND">tar</tt></td> -</tr> -</table> -</div> -</body> -</html> - |
