Name
       cat - concatenate and print data

Syntax
       cat [ -b ] [ -e ] [ -n ] [ -s ] [ -t ] [ -u ] [ -v ] file...

Description
       The command reads each file in sequence and displays it on the standard
       output.	Therefore, to display the file	on  the	 standard  output  you
       type:
       cat file
       To concatenate two files and place the result on the third you type:
       cat file1 file2 > file3
       To concatenate two files and append them to a third you type:
       cat file1 file2 >> file3
       If  no input file is given, or if a minus sign (-) is encountered as an
       argument, 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 utility supports the processing of 8-bit
       characters.

Options
       -b   Ignores  blank  lines  and precedes each output line with its line
	    number.

       -e   Displays a dollar sign ($) at the end of each output line.

       -n   Precedes all output lines (including blank lines) with  line  num‐
	    bers.

       -s   Squeezes  adjacent	blank lines from output and single spaces out‐
	    put.

       -t   Displays non-printing characters (including tabs) in  output.   In
	    addition to those representations used with the -v option, all tab
	    characters are displayed as ^I.

       -u   Unbuffers output.

       -v   Displays non-printing characters (excluding tabs and  newline)  as
	    the	 ^x.   If  the	character  is in the range octal 0177 to octal
	    0241, it is displayed as M-x. The delete  character	 (octal	 0177)
	    displays as ^?.  For example, is displayed as ^X.

Restriction
       Do not redirect output to one of the input files using the > (redirect‐
       ion symbol).  If you do this, you lose the original data in  the	 input
       file because the shell truncates it before can read it.
