.Op Fl n

|
|
.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.
|
|
Note that this option as well as the effect of
|
|
.Ql \ec
|
|
are implementation-defined in
|
|
.St -p1003.1-2001
|
|
as amended by Cor. 1-2002.
|
|
Applications aiming for maximum
|
|
portability are strongly encouraged to use
|
|
.Xr printf 1
|
|
to suppress the newline character.
|
|
.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.
