    NAME
         cat - catenate and print

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

    DESCRIPTION
         Cat reads each file in sequence and displays it on the stan-
         dard 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 encoun-
         tered, 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 character (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.
