- -s file

- 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 -)
A number to brag to your friends about
$ dd if=/dev/zero bs=80k count=60k 2> /dev/null | ./pipebench -q >
/dev/null
