The s6-cat program

s6-cat copies stdin to stdout.

Interface

     s6-cat

s6-cat transfers data from stdin to stdout, until it receives EOF or gets killed.

Notes

On systems that support it (as of 2.0.0.0, only Linux 2.6.17 or later), s6-cat performs zero-copy transfer.

Posixness

s6-cat is not suitable as a Single Unix cat program.
