4. Using bzip2 with tar

Listed below are three ways to use bzip2 with tar, namely

4.1 Easiest to set up:

This method requires no setup at all. To un-tar the bzip2'd tar archive, foo.tar.bz2 in the current directory, do

/path/to/bzip2 -cd foo.tar.bz2 | tar xf -

tar --use-compress-prog=bzip2 xf foo.tar.bz2

These work, but can be a PITA to type often.

4.2 Easy to set up, fairly easy to use, no need for root privileges:

Thanks to Leonard Jean-Marc for the tip. Thanks also to Alessandro Rubini for differentiating bash from the csh's.

In your .bashrc, you can put in a line like this:

alias btar='tar --use-compress-program /usr/local/bin/bzip2 '

In your .tcshrc, or .cshrc, the analogous line looks like this:

alias btar 'tar --use-compress-program /usr/local/bin/bzip2'

4.3 Also easy to use, but needs root access.

Update your tar to GNU's newest version, which is currently 1.13.10. It can be found at GNU's ftp site or any mirror.
