+.Dd May 31, 1993
+.Dt ECHO 1
+.Os
+.Sh NAME
+.Nm echo
+.Nd produce message in a shell script
+.Sh SYNOPSIS
+.Nm
+.Op Fl n | Fl e
+.Ar args ...
+.Sh DESCRIPTION
+.Nm
+prints its arguments on the standard output, separated by spaces.
+Unless the
+.Fl n
+option is present, a newline is output following the arguments.
+The
+.Fl e
+option causes
+.Nm
+to treat the escape sequences specially, as described in the following
+paragraph.
+The
+.Fl e
+option is the default, and is provided solely for compatibility with
+other systems.
+Only one of the options
+.Fl n
+and
+.Fl e
+may be given.
+.Pp
+If any of the following sequences of characters is encountered during
+output, the sequence is not output. Instead, the specified action is
+performed:
+.Bl -tag -width indent
+.It Li \eb
+A backspace character is output.
+.It Li \ec
+Subsequent output is suppressed. This is normally used at the end of the
+last argument to suppress the trailing newline that
+.Nm
+would otherwise output.
+.It Li \ef
+Output a form feed.
+.It Li \en
+Output a newline character.
+.It Li \er
+Output a carriage return.
+.It Li \et
+Output a (horizontal) tab character.
+.It Li \ev
+Output a vertical tab.
+.It Li \e0 Ns Ar digits
+Output the character whose value is given by zero to three digits.
+If there are zero digits, a nul character is output.
+.It Li \e\e
+Output a backslash.
+.El
+.Sh HINTS
+Remember that backslash is special to the shell and needs to be escaped.
+To output a message to standard error, say
+.Pp
+.D1 echo message \*[Gt]\*[Am]2
+.Sh BUGS
+The octal character escape mechanism
+.Pq Li \e0 Ns Ar digits
+differs from the
+C language mechanism.
+.Pp
+There is no way to force
+.Nm
+to treat its arguments literally, rather than interpreting them as
+options and escape sequences.
