CAT(1)                                                     CAT(1)

     NAME
          cat, read - catenate files

     SYNOPSIS
          cat [ file ... ]
          read [ file ]

     DESCRIPTION
          Cat reads each file in sequence and writes it on the stan-
          dard 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 one line from the named file to standard output.
          It is useful in interactive rc(1) scripts.

     DIAGNOSTICS
          Read exits with status eof on end of file.

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