	38	.Sh NAME
	39	.Nm echo
	40	.Nd write arguments to the standard output
	41	.Sh SYNOPSIS
	42	.Nm
	43	.Op Fl n
	44	.Op Ar string ...
	45	.Sh DESCRIPTION
	46	The
	47	.Nm
	48	utility writes any specified operands, separated by single blank
	49	.Pq Ql "\ "
	50	characters and followed by a newline
	51	.Pq Ql \en
	52	character, to the standard
	53	output.
	54	.Pp
	55	The following option is available:
	56	.Bl -tag -width flag
	57	.It Fl n
	58	Do not print the trailing newline character.
	59	This may also be achieved by appending
	60	.Ql \ec
	61	to the end of the string, as is done
	62	by iBCS2 compatible systems.
	63	Note that this option as well as the effect of
	64	.Ql \ec
	65	are implementation-defined in
	66	.St -p1003.1-2001
	67	as amended by Cor.\& 1-2002.
	68	Applications aiming for maximum
	69	portability are strongly encouraged to use
	70	.Xr printf 1
	71	to suppress the newline character.
	72	.El
	73	.Pp
	74	Some shells may provide a builtin
	75	.Nm
	76	command which is similar or identical to this utility.
	77	.\" 4874742
	78	Most notably, the builtin
	79	.Nm
	80	in
	81	.Xr sh 1
	82	does not accept the
	83	.Fl n
	84	option.
	85	.\" 4874742
	86	Consult the
	87	.Xr builtin 1
	88	manual page.

	97	The
	98	.Nm
	99	utility conforms to
	100	.St -p1003.1-2001
	101	as amended by Cor.\& 1-2002.
