# pipebench(1)

Shows speed of stdin/stdout communication

## NAME

pipebench - Shows speed of stdin/stdout communication

## SYNOPSIS

**pipebench** \[ -ehqQIoru \] \[ -s *file* \| -S *file* \]  \[ -b *bufsize* \]

## DESCRIPTION

Measures the speed of stdin/stdout communication.

## OPTIONS

-

  - \-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 convert to units (kilo, Mega, etc...)
