NAME
       cat - catenate and print

SYNOPSIS
       cat [ -u ] file ...

DESCRIPTION
       Cat reads each file in sequence and writes it on the standard output.  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  file  is  given,  or  if the argument `-' is encountered, cat reads from the standard input.  Output is buffered in 512-byte blocks
       unless the standard output is a terminal or the -u option is present.

SEE ALSO
       pr(1), cp(1)

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