[comp.unix.questions] how to delete a file from a tar?

sun@nntp-server.caltech.edu (Suneal K. Chaudhary) (03/31/91)

I've been using the Sun floppy disk drive as according to the
manual, and ive made a few floppies with tar.  But now i
want to know how to delete files from the tar without unpacking
the tar totally and then repacking it.  Im on a 
sparcstation 1+, and im using 1.44mb floppies.  i use
the device /dev/rfd0 (i think).  thanks in advance.

  The filesystem overhead on a floppy is pretty high.  You can get a lot more
data on the disk using tar than you can if you need to allocate all the space
necessary to store the structure of a filesystem.

  Incidentally, Mike, why is it that half of your messages don't have a From:
line in the header?  RFC 1036 says that a From: line is required, and it's
annoying when my news reader can't show me who the message is from and when
attribution lines (like the one above) can't figure out what name to put in
because there's not From:.
