NAME
	  echo - Writes	its arguments to standard output

     SYNOPSIS
	  echo [-n] [string ...]


	  The echo command writes the specified	string to standard
	  output.

     FLAGS
	  -n  No newline is added to the output.


     DESCRIPTION
	  The arguments	are separated by spaces	and a newline charac-
	  ter follows the last string.	Use echo to produce diagnostic
	  messages in command files and	to send	data into a pipe.

	  The echo command described here is the program
	  /usr/bin/echo.  Both csh and sh contain built-in echo	sub-
	  commands, which do not necessarily work in the same way as
	  the /usr/bin/echo command.

	  The echo command recognizes the following special charac-
	  ters:


	  \b  Displays a backspace character.

	  \c  Suppresses the newline character.

	  \f  Displays a formfeed character.

	  \n  Displays a newline character.

	  \r  Displays a carriage-return character.

	  \t  Displays a tab character.

	  \\  Displays a backslash character.

	  \number
	      Displays an 8-bit	character whose	value is the 1-, 2- or
	      3-digit octal number, number.  The first digit of	number
	      must be a	0 (zero).


     EXAMPLES
	   1.  To write	a message to standard output, enter:

	       echo Please insert diskette . . .



	   2.  To display a message containing special characters as
	       listed in DESCRIPTION, enclose the message in quotes,
	       as follows:

	       echo "\n\n\nI'm at lunch.\nI'll be back at 1 p.m."



	       This skips three	lines and displays the message:

	       I'm at lunch.
	       I'll be back at 1 p.m.



	       Note that you must enclose the message in quotation
	       marks if	it contains escape sequences such as \n.  Oth-
	       erwise, the shell treats	the \ (backslash) as an	escape
	       character.  The above command, entered without the
	       quotes, results in the following	output:

	       nnnI'm at lunch.nI'll be	back at	1 p.m.



	   3.  To use echo with	pattern-matching characters, enter:

	       echo The	back-up	files are: *.bak



	       This displays the message The back-up files are:	and
	       then displays the filenames in the current directory
	       ending with .bak.

	   4.  To add a	single line of text to a file, enter:

	       echo Remember to	set the	shell search path to $PATH. >>notes



	       This adds the message to	the end	of the file notes
	       after the shell substitutes the value of	the PATH shell
	       variable.

	   5.  To write	a message to the standard error	output (sh
	       only), enter:

	       echo Error: file	already	exists.	>&2



	       Use this	in shell procedures to write error messages.
	       If the >&2 is omitted, then the message is written to
	       the standard output.
