If your disk is mounted at root ("/"), which is the case of most default distro installs, you can run "df -h /" to get only your disk info:

    user@hostname:~$ df -h /
    Filesystem      Size  Used Avail Use% Mounted on
    /dev/sdc       1007G   49G  908G   6% /

This only shows a single disk.

I find it weird that despite having a bunch of options to control output and even filter things, df does not have an option to specify "show me only physical block devices and only once (my /dev/sda4 shows up for various mountpoints but still all show the same size/used/avail values)".

In that case, you can use "-t ext4" (or whatever filesystem type you use) to show only disks formatted with this filesystem type.

On my machine, none of the snap/tmpfs/efivars stuff shows up:

    user@hostname:~$ df -ht ext4
    Filesystem      Size  Used Avail Use% Mounted on
    /dev/sdc       1007G   49G  908G   6% /
