は、各引数の間を 1 つの空白文字
|
|
.Pq Ql "\ "
|
|
で区切り、最後に改行
|
|
.Pq Ql \en
|
|
を付加したものを標準出力に書き出します。
|
|
.Pp
|
|
オプションとしては以下のものがあります:
|
|
.Bl -tag -width flag
|
|
.It Fl n
|
|
改行を付加しません。
|
|
これは、iBCS2 互換システムで行われていたように、
|
|
文字列の最後に
|
|
.Ql \ec
|
|
を付け加える事でも実現できます。
|
|
本オプションおよび
|
|
.Ql \ec
|
|
の効果は、Cor.\& 1-2002 で修正されたように
|
|
.St -p1003.1-2001
|
|
では実装依存です。
|
|
最大の可搬性を目指すアプリケーションは、改行文字を抑制するために
|
|
.Xr printf 1
|
|
を使用することが強く勧められています。
