And a good thing, too, because that syntax is completely wrong.
wooledg:~$ sudo x=$(id)
usage: sudo -h | -K | -k | -V

wooledg:~$ sudo x=$(df -h)
[sudo] password for wooledg:
sudo: Size: command not found
I think what Albretch was *trying* to do was this:
_DF=$(sudo df -h)
which would work, but as Tomas said, the sudo is just not needed.
P.S. see <https://mywiki.wooledge.org/BashFAQ/094> for more information
on parsing df output, in general.
