Output from ls has newlines but displays on a single line. Why?

I think I may be overlooking a relatively fundamental point regarding shell. Output from the **ls** command by default separates output with newlines, but the shell displays the output on a single line. Can anyone explain this to me? I had always presumed that the output was simply separated by spaces, but now that I see the output separated by newlines, I would expect the output to be displaying on separate lines. Example: cpoweradm@debian:~/lpi103-4$ ls text* text1 text2 text3 **od** shows that the output is separated by newlines: cpoweradm@debian:~/lpi103-4$ ls text* | od -c 0000000 t e x t 1 \n t e x t 2 \n t e x t 0000020 3 \n 0000022 If newlines are present, then why doesn't the output display as: text1 text2 text3
