To whom it may concern,
First I want to say that I admire your (GNU's) work. Second I would
like to make a suggestion in reguards to TAR. I am using tar to create
backups for my systems. I store these backups in two places, a massive
storage system (that I don't have direct control over) and on CDR's. On
the Massive Storage system, everything fits into one file. On the CDR's
it spans several volumes. I want to be able to save the tar archive to the
Mass Store as a single file first, then at a later date, create the CDR
copy as a Multi-volume archive without storing to an intermediate
location. At first I was going to pipe the data to to tar and have tar
create a multi-volume archive to put on CDR's. Unfortunately I cann't
figure out how to get tar to create an archive from standard input.
What I would like to do is:
foo my.tar.gz | tar -xzOf - | tar -cMf - -L 650000 - | bar
where 'foo' is a program that retrieves the archive and streams it to
stdout and bar is a program that streams the stdin to CDR. The only thing
I am missing is the ablity to have tar interpret the '-' at the end as
'read from stin' or some flag ( -I Maybe ) similar to the -O flag but for
stdin.
I don't know if I just overlooked something, but this seems like the most
logical way to transfer archives between media of different sizes. If
there is a method to do this that I am just too dense to find, I would be
most gratefull if you could point in the right direction. If not, what do
you think about adding this to TAR.
Thanks,
-Dennis

In theory, there is no difference between theory and practice. In practice,
there is.
