FW: +N option in tail command

[נחשון ישורון/Nachshon Yeshurun]

Hello

Man pages for the tail command shows the ability to use the +N option.
Yet, attempting it on Ubuntu 9.10 results in an error.
Is this a bug?

>From man pages:

      -n, --lines=N
              output the last N lines, instead of the last 10; or  use  +N  to
              output lines starting with the Nth


Attempting the command:

address@hidden:~/temp$ tail +5 /etc/passwd
tail: cannot open `+5' for reading: No such file or directory
==> /etc/passwd <==
