Using bzip2 with tar</A></H2> <P>Listed below are three ways to use bzip2 with tar, namely <H2><A NAME="ss4.1">4.1 Easiest to set up:</A> </H2> <P>This method requires no setup at all. To un-tar the bzip2'd tar archive, foo.tar.bz2 in the current directory, do <BLOCKQUOTE><CODE> <PRE> /path/to/bzip2 -cd foo.tar.bz2 | tar xf - </PRE> </CODE></BLOCKQUOTE> or <BLOCKQUOTE><CODE> <PRE> tar --use-compress-prog=bzip2 xf foo.tar.bz2 </PRE> </CODE></BLOCKQUOTE> <P> <P>These work, but can be a PITA to type often. <P> <H2><A NAME="ss4.2">4.2 Easy to set up, fairly easy to use, no need for root privileges:</A> </H2> <P> Thanks to <A HREF="mailto:leonard@sct1.is.belgacom.be">Leonard Jean-Marc</A> for the tip. Thanks also to <A HREF="mailto:rubini@morgana.systemy.it">Alessandro Rubini</A> for differentiating bash from the csh's. <P> <P>In your .bashrc, you can put in a line like this: <BLOCKQUOTE><CODE> <PRE> alias btar='tar --use-compress-program /usr/local/bin/bzip2 ' </PRE> </CODE></BLOCKQUOTE> <P> <P>In your .tcshrc, or .cshrc, the analogous line looks like this: <BLOCKQUOTE><CODE> <PRE> alias btar 'tar --use-compress-program /usr/local/bin/bzip2' </PRE> </CODE></BLOCKQUOTE> <P> <H2><A NAME="ss4.3">4.3 Also easy to use, but needs root access.</A> </H2> <P>Update your tar to GNU's newest version, which is currently 1.13.10. It can be found at <A HREF="ftp://alpha.gnu.org/gnu/tar/">GNU's ftp site</A> or any mirror. <P> <HR> <A HREF="Bzip2-5.html">Next</A> <A HREF="Bzip2-3.html">Previous</A> <A HREF="Bzip2.html#toc4">Contents</A> </BODY> </HTML>
