CAT(1)                  GENIX Programmer's Manual                  CAT(1)



      NAME
           cat - catenate and print

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

      DESCRIPTION
           Cat reads each file in sequence and writes it on the  standard  out-
           put.  Thus

                          cat file

           prints the file, 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
           1024-byte blocks unless the standard output is a terminal, in  which
           case  it  is  line  buffered.  The -u option causes the output to be
           completely unbuffered.

           The option -n causes the output lines to  be  numbered  sequentially
           from  1.   Giving -b with -n causes numbers to be omitted from blank
           lines.

           The option -s causes the output to be single spaced by crushing  out
           multiple adjacent empty lines.

           The option -v causes non-printing characters  to  be  printed  in  a
           visible  way.   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  -v  and
           causes the ends of lines to be followed by the character `$'; the -t
           option with -v causes tabs to be printed as ^I.

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