CAT(1)                  COMMAND REFERENCE                  CAT(1)



NAME
     cat - catenate and print

SYNOPSIS
     cat [ -b ] [ -e ] [ -n ] [ -s ] [ -t ] [ -u ] [ -v ] [
     filename ... ]

DESCRIPTION
     Cat reads each filename 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 dash argument (-) is
     encountered, cat reads from the standard input.  Output is
     buffered in 1024-byte blocks unless the standard output is a
     terminal, in which case it is line buffered.

OPTIONS
     -b  Displays the non-blank output lines preceded by line
         numbers, sequentially numbered from one.

     -e  Similar to -v, with the exception that it displays a $
         character at the end of each line.

     -n  Displays the output lines preceded by line numbers,
         sequentially numbered from one.

     -s  Removes multiple empty lines, leaving only one blank
         line. Note that a line which contains only blanks and
         tabs is not an empty line.

     -t  Similar to -v, with the exception that it displays tab
         characters as ^I.

     -u  Causes the output to be completely unbuffered.

     -v  Displays non-printing characters so that they are
         visible.  Control characters print like ^X for <CTRL-X>
         (except for tabs which continue to be expanded); 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.

EXAMPLES
     The following example concatenates the files tmp.1, tmp.2
     and tmp.3 onto standard output.



          cat tmp.1 tmp.2 tmp.3


DIAGNOSTICS
     cat: Output is going to be written on input file file
         Cat displays this message if you try to redirect its
         output to a file which was one of the input files -- in
         other words, cat won't overwrite one of its input files.
         (See note below.)

RETURN VALUE
     [NO_ERRS]      Command completed without error.

     [NP_WARN]      An error warranting a warning message
                    occurred. Execution continues.

     [P_WARN]       A system error occurred. Execution continues.
                    See intro(2) for more information on system
                    errors.

CAVEATS
     Sh(1sh) redirection such as cat a b >a and cat a b >b, may
     destroy the input files before reading them.
