-S file

-I  Use 1kB = 1000B, instead of the default 1024B.

-u  Don't convet to units (kilo, Mega, etc...)

EXAMPLES
Benchmark and show progress of backup
# (cd /home/; tar cf - .) | pipebench | (cd /mnt/backup/; tar xf -)

$ dd if=/dev/zero bs=80k count=60k 2> /dev/null | ./pipebench -q > /dev/null
