Yes, there are a few alternative ways to phrase the same thing. For example:
cd /
tar -cf /backup/tarball.tar --one-file-system .
tar -c --one-file-system -f /backup/tarball.tar .
You can combine the options of tar in almost *any* order with a bit of
care. For example, here's a small part of my incremental backup script:
cd /home/keramida/.zfs/snapshot/today
env TZ=UTC tar -c --one-file-system --newer-mtime '2009-11-20 00:00:00' \
-f '/backup/home.keramida.2009-11-20.tar' .

I think my reply went to the previous post, but here is

Long options (preceded by --) are only supported directly on systems that
have the getopt_long(3) function. The -W option can be used to access long
options on systems that do not support this function.
}
Or is there another synopsis?
Thanks!

Long options (preceded by --) are only supported directly on systems that
have the getopt_long(3) function. The -W option can be used to access long
options on systems that do not support this function.
}
Or is there another synopsis?
Thanks!
