+.Sh NAME
+.Nm echo
+.Nd write arguments to the standard output
+.Sh SYNOPSIS
+.Nm echo
+.Op Fl Een
+.Op Ar string ...
+.Sh DESCRIPTION
+The
+.Nm
+utility writes any specified operands, separated by single blank
+.Pq Sq \ \&
+characters and followed by a newline
+.Pq Sq \en
+character, to the standard
+output.
+.Pp
+When no operands are given, only the newline is written.
+The
+.Fl \-
+operand,
+which generally denotes an end to option processing,
+is treated as part of
+.Ar string .
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl E
+Disable interpretation of backslash escape sequences (default).
+.It Fl e
+Enable interpretation of the following backslash escape sequences:
+.Pp
+.Bl -tag -width Ds -offset indent -compact
+.It Cm \e\e
+A literal backslash.
+.It Cm \ea
+Alert (BEL).
+.It Cm \eb
+Backspace.
+.It Cm \ec
+Suppress further output, including the trailing newline character.
+.It Cm \ee
+Escape character.
+.It Cm \ef
+Form feed.
+.It Cm \en
+Newline.
+.It Cm \er
+Carriage return.
+.It Cm \et
+Horizontal tab.
+.It Cm \ev
+Vertical tab.
+.It Cm \e0 Ns Ar nnn
+The character whose octal value is
+.Ar nnn
+(zero to three octal digits).
+.It Cm \ex Ns Ar hh
+The character whose hexadecimal value is
+.Ar hh
+(one or two hexadecimal digits).
+.El
+.It Fl n
+Do not print the trailing newline character.
+.El
+.Sh EXIT STATUS
+.Ex -std echo
+.Sh SEE ALSO
+.Xr csh 1 ,
+.Xr ksh 1 ,
+.Xr printf 1
+.Sh STANDARDS
+The
+.Nm
+utility is compliant with the
+.St -p1003.1-2008
+specification.
+.Pp
+The flags
+.Op Fl E ,
+.Op Fl e ,
+and
+.Op Fl n
+conflict with the behaviour mandated by the
+X/Open System Interfaces option of the
+.St -p1003.1-2008
+specification,
+which says they should be treated as part of
+.Ar string .
+.Pp
+.Nm
+also exists as a built-in to
+.Xr csh 1
+and
+.Xr ksh 1 ,
+though with a different syntax.
+.Pp
+Where portability is paramount, use
+.Xr printf 1 .
+.Sh HISTORY
+An
+.Nm
+utility appeared in
+.At v2 .
