DESCRIPTION¶

Measures the speed of stdin/stdout communication.

-h

Displays a help message and exits.

-r

Just show raw speed, no fancy stuff. And no summary.

-s file

Write status to file instead of stderr.

-S file

Write status to file instead of stderr.

-I

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

-u

Don't convert to units (kilo, Mega, etc...)

EXAMPLES¶

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