null -- Device Driver

The `bit bucket'

All data written to the special file /dev/null are thrown away (sent to the
``bit bucket'').   This is  useful, for  example, when you  wish to  test a
program's side effects while ignoring its output.

A read from  file /dev/null returns end of file  (zero bytes of data).  The
shell sh uses /dev/null as input to background processes.
