pipebench - Shows speed of stdin/stdout communication
pipebench [ -ehqQIoru ] [ -s file | -S file ]
[ -b bufsize ]
Measures the speed of stdin/stdout communication.
- -h
- Displays a help message and exits.
- -e
- If an error occurs, exit (breaking the pipe between stdin and stdout. By
default an error message is printed to stderr and the program
continues.
- -q
- Only show summary stats.
- -Q
- Don't show running speed or summary stats. Same as -q -o. Can be used to
play with buffer size.
- -o
- Don't show summary.
- -b bufsize
- Use this buffer size, in bytes.
- -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 convet to units (kilo, Mega, etc...)
Benchmark and show progress of backup

A number to brag to your friends about
