Update a tarball

This will update the tarball, adding files that have changed since the last update.

This assumes that the tarball is in the same directory as the files being archived.

N.B. This command can't be used on compressed tarballs.

N.B. This will add the updated files to the tarball, so that the tarball will have two versions of each file. This will make the tarball larger, but doesn't have any other significant effect.

What others think

So what happens upon untarring, is the first file written and then promptly overwritten by the newer version? The order of untarring would matter greatly.

tar's default is to only untar the most recent file added to the tarball. So, when untarring you will only get the most recent one.
