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.

NAME

       cat - catenate and print

SYNOPSIS

       cat [ -u ] [ -n ] [ -s ] [ -v ] file ...

DESCRIPTION

       Cat reads each file in sequence and displays it on the standard output.	Thus

       cat file

       displays the file on the standard output, and

       cat file1 file2 >file3

       concatenates the first two files and places the result on the third.

       If  no input file is given, or if the argument `-' is encountered, cat reads from the standard input file.  Output is buffered in the block
       size recommended by stat(2) unless the standard output is a terminal, when it is line buffered.	The -u option makes the output	completely
       unbuffered.

       The  -n	option	displays  the  output lines preceded by lines numbers, numbered sequentially from 1.  Specifying the -b option with the -n
       option omits the line numbers from blank lines.

       The -s option crushes out multiple adjacent empty lines so that the output is displayed single spaced.

       The -v option displays non-printing characters so that they are visible.  Control characters print like ^X for control-x; the delete  char-
       acter  (octal  0177)  prints as ^?.  Non-ascii characters (with the high bit set) are printed as M- (for meta) followed by the character of
       the low 7 bits.	A -e option may be given with the -v option, which displays a `$' character at the end of each line.   Specifying  the	-t
       option with the -v option displays tab characters as ^I.

BUGS

       Beware of `cat a b >a' and `cat a b >b', which destroy the input files before reading them.
