This should work, on all systems conforming to POSIX
(which surely HP-UX does):

df | tail -n +2

"tail +2" isn't portable.

Hello maintainer,

running    tail  +2   on an Ubuntu Box I get the following error:
df | tail +2
tail: cannot open `+2' for reading: No such file or directory

df | tail -lines +2 works OK

I support HP-UX, Redhat and Ubuntu systems and unfortunately the -lines option does not work on my legacy HP-UX systems.

The man page for tail says
       -n, --lines=N
              output the last N lines, instead of the last 10; or  use  +N  to
              output lines starting with the Nth

Here is the version of coreutils which I am running:

#dpkg -s coreutils
