NAME

       recordio - records the input and output of a program.

SYNOPSIS

       recordio prog

DESCRIPTION

       recordio runs prog.  It prints lines to descriptor 2 showing the input and output of prog.

       At the beginning of each line on descriptor 2, recordio inserts the prog process ID, along
       with < for input or > for output. At the end of each line it inserts +, a space, or [EOF];
       a  space  indicates  that there was a new line in the input or output, and [EOF] indicates
       the end of input or output.

       recordio prints every packet of input and output  immediately.  It  does  not  attempt  to
       combine packets into coherent lines. For example,

              recordio sh -c 'cat /dev/fd/8 2>&1' > /dev/null

       could produce

            5135 > cat: /dev/fd/8: Bad file descriptor
            5135 > [EOF]

       or

            5135 > cat: +
            5135 > /dev/fd/8+
            5135 > : +
            5135 > Bad file descriptor
            5135 > [EOF]

       if the cat program prints several packets.

       recordio  uses  several  lines  for  long  packets  to guarantee that each line is printed
       atomically.

       recordio runs as a child process of prog.  It exits when it sees the end of prog's output.
