recordio(1)                                           recordio(1)


NAME
       recordio - records the input and output of a program.

SYNOPSIS
       recordio prog

DESCRIPTION
       recordio runs prog.  It prints lines to descriptor 2 show-
       ing 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 immedi-
       ately. It does not attempt to combine packets into  coher-
       ent 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.
