NAME

       recordio - record the input and output of a program

SYNTAX

       recordio program [ arg ...  ]

DESCRIPTION

       recordio  runs  program  with  the given arguments.  It prints lines to stderr showing the
       input and output of program.

       At the beginning of each line on stderr, recordio inserts the program  process  ID,  along
       with  <  for  input  or  > for output.  At the end of each line it inserts a space, a plus
       sign, or [EOF]; a space indicates that there was a newline 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 stderr 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]

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

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