ECHO(1)								       ECHO(1)

NAME    [Toc]    [Back]

     echo - echo arguments

SYNOPSIS    [Toc]    [Back]

     echo [ -n ] [ arg ] ...

DESCRIPTION    [Toc]    [Back]

     echo writes its arguments separated by blanks and terminated by a newline
 (except when "-n" is specified, see below) on	the standard output.
     It	also understands C-like	escape conventions; beware of conflicts	with
     the shell's use of	\:

	  \b   backspace
	  \c   print line without new-line
	  \f   form-feed
	  \n   new-line
	  \r   carriage	return
	  \t   tab
	  \v   vertical	tab
	  \\   backslash
	  \0n  where n is the 8-bit character whose ASCII code is the 1-, 2-
	       or 3-digit octal	number representing that character.

     echo has two operating modes.  By default,	echo operates compatibly with
     certain earlier versions of System	V echo.	If the environment variable
     _XPG is defined, and has a	numeric	value greater than 0, echo operates in
     conformance with the X/Open XPG4 specifications. In this mode, when -n is
     specified,	it is treated as a string, like	any other arguments.  In the
     backward compatibility mode, when -n is specified,	it means "no newline".
 The	arguments will not be terminated by a new-line on the standard

     echo is useful for	producing diagnostics in command files and for sending
     known data	into a pipe.

SEE ALSO    [Toc]    [Back]

     csh(1), sh(1).

CAVEATS    [Toc]    [Back]

     When representing an 8-bit	character by using the escape convention \0n,
     the n must	always be preceded by the digit	zero (0).

     For example, typing:  echo	'WARNING:\07' will print the phrase WARNING:
     and sound the ``bell'' on your terminal.  The use of single (or double)
     quotes (or	two backslashes) is required to	protect	the ``\'' that
     precedes the ``07''.
     For the octal equivalents of each character, see ascii(5).

     echo is often a builtin to	the shells, see	the shell man pages for
     feature specific to each shell.  This man page documents the executable
     program, not the builtin versions,	although they are similar.
