Hello

split.c wastes file descriptor:

cpu% split -e '^From' /n/ken/usr/spool/mail/arisawa
split 1297714: warning: process exceeds 100 file descriptors


The file descriptor is created and discarded in openf(void):

void
openf(void)
{
	int fd;
	Bflush(output);
	Bterm(output);
	fd = create(name,OWRITE,0666);
	if(fd < 0) {
		fprint(2, "grep: can't create %s: %r\n", name);
		exits("create");
	}
	Binit(output, fd, OWRITE);
}
