.Sh SYNOPSIS
.Nm
.Op Fl n
.Op Ar string ...
.Sh DESCRIPTION
The
.Nm
utility writes any specified operands, separated by single blank
.Pq Ql "\ "
characters and followed by a newline
.Pq Ql \en
character, to the standard
output.
.Pp
The following option is available:
.Bl -tag -width flag
.It Fl n
Do not print the trailing newline character.  This may also be
achieved by appending
.Ql \ec
to the end of the string, as is done
by iBCS2 compatible systems.
.El
.Pp
Some shells may provide a builtin
.Nm
command which is similar or identical to this utility.
Consult the
.Xr builtin 1
manual page.
.Sh DIAGNOSTICS
.Ex -std
.Sh SEE ALSO
.Xr builtin 1 ,
.Xr csh 1 ,
.Xr printf 1 ,
.Xr sh 1
.Sh STANDARDS
The
.Nm
utility is expected to be
.St -p1003.2
compatible.

Well, it would appear that the "ayes" have it (though by a slim margin). Apply my \c changes to echo. It should also be noted that this is: A) going into 2.2, not 2.1 B) a functional no-op unless you actually use it! 1995-08-31 17:25:55 +00:00			`Do not print the trailing newline character.

Improve shell documentation: * Consistently misspell built-in as builtin. * Add a builtin(1) manpage and create builtin(1) MLINKS for all shell builtin commands for which no standalone utility exists. These MLINKS replace those that were created for csh(1). * Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages, as well as to the manpages of standalone utilities which are supported as shell builtin commands in at least one of the shells. In such manpages, explain that similar functionality may be provided as a shell builtin command. * Improve sh(1)'s description of the cd builtin command. Csh(1) already describes it adequately. Replace the cd(1) manpage with a builtin(1) MLINKS link. * Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use Ic instead of Xr for shell builtin commands. * Undo English contractions.

Correct some hard sentence breaks. Only those surrounding the previous commit and those which cause ugly nroff output have been fixed, since the purpose of the style guideline which they contravene is to reduce the sizes of deltas.
