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, read, nobs - catenate files

SYNOPSIS

       cat [ file ...  ]
       read [ -m ] [ -n nline ] [ file ...  ]
       nobs [ file ...	]

DESCRIPTION

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

	      cat file

       prints a file and

	      cat file1 file2 >file3

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

       If no file is given, cat reads from the standard input.	Output is buffered in blocks matching the input.

       Read copies to standard output exactly one line from the named file, default standard input.  It is useful in interactive rc(1) scripts.

       The -m flag causes it to continue reading and writing multiple lines until end of file; -n causes it to read no more than nline lines.

       Read  always  executes  a single write for each line of input, which can be helpful when preparing input to programs that expect line-at-a-
       time data.  It never reads any more data from the input than it prints to the output.

       Nobs copies the named files to standard output except that it removes all backspace characters and the characters that precede them.  It is
       useful to use as $PAGER with the Unix version of man(1) when run inside a win (see acme(1)) window.

DIAGNOSTICS

       Read exits with status eof on end of file or, in the -n case, if it doesn't read nlines lines.

BUGS

       Beware of and which destroy input files before reading them.
