Ну это специфично *BSD (может быть еще где есть). POSIX про такое не знает, у paste(1) такой функциональности нет.

Очень странно.
У меня с помощью paste проходит.

jot `wc -l /etc/termcap | awk '{print $1;}'` 1 | paste -d"<LF>" - /etc/termcap | head

Я что-то не так делаю?

И какое это имеет отношение к смешению двух файлов?

sergey_m

cat inp1.txt inp2.txt > out.txt

Садись, двойка.

Ivan8209

Смешивает.
Через строку.

И чем твоя конструкция с awkами и прочим лучше предложенной в конце изначального треде? Просто lam конечно будет быстрее всего, но не тройной конвейер с paste.
Короче вывод такой: самое лучшее решение lam, но он не описан в POSIX.

sergey_m

Ты прав. Посыпаю голову пеплом.
