Once upon a time you could use the command 'mount' to see what filesystems were mounted but it has now got so cluttered with 'virtual' filesystems that it's pretty useless.

What's an easy way of seeing what actual, data containing, useful filesystems are mounted? I.e. the physical disks and the NFS ones.

Wellllll, for physical only, lsblk -f may be much nicer output for you...

For nfs too, then...

mount -t ext2,ext3,ext4,xfs,btrfs,vfat,nfs,smbfs

Should fairly much get you everything.

Yes, that's the sort of filtering I want, I think that's going to become a script or an alias. It's a pity that you can't set a default configuration for mount so that the above is the default when you say 'mount' but allows one to use mount normally otherwise.

In the mount man page it says:-

The listing mode is maintained for backward compatibility only.

For more robust and customizable output use findmnt(8), especially in your scripts.

However findmnt has the same problem as mount, it lists *everything*, I get:-

I quite like the layout but I could do without all those cgroup entries in particular. However like mount findmnt doesn't have any way to filter the output with environment or configuration.
