I can reproduce this on my FreeBSD box, but I cannot figure out how this works? Can you really send a never ending stream to nroff? And why do you need seq? I get the same result with just head: $ ( printf '.pl 1i\n.ll 2i\n' ; yes 'a \n%' ) | nroff | head -n13 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 1 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 2 a 3 a 3 a 3 a 3 a 3 $ Anton
