I'm getting mighty tired of having to manually egrep out NFS- and SMB-mounted filesystems whenever I am checking on the condition of locally-mounted filesystems. So, my question is thus: is there some combination of flags that I can pass to either df or mount that will force them to display ONLY local filesystems and skip any and all network-mounted ones?

df -l. This depends on network filesystems being properly identified as such, though.

    Super, very straightforward solution. – рüффп Nov 15 '18 at 14:09

    df -l still shows many loop-devices like /snap/gnome-calculator or /snap/core/ – maletin Apr 1 '19 at 19:04
  • What does "property identified" mean? Must it have the _netdev mount option, or is it some other detection logic in the background? – bviktor Nov 26 '19 at 9:00

Okay, as seems to be the case 75% of the time, I've actually tripped over the answer to my own question. The -t and -x flags for df will do what I'm looking for.

-t [type] will list filesystems matching fs TYPE [type]

-x [type] will list filesystems NOT matching fs TYPE [type]

I.e., for me to exclude NFS-mounted filesystems, the command is df -x nfs.
