I'm getting mighty tired of having to manually egrep out NFS- and SMB-mounted file systems whenever I am checking on the condition of locally-mounted file systems.

Is there some combination of flags that I can pass to either df or mount that will force them to display only local file systems 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.

    df -l still shows many loop-devices like /snap/gnome-calculator or /snap/core/

  • What does "property identified" mean? Must it have the _netdev mount option, or is it some other detection logic in the background?

The -t and -x flags for df will do what I'm looking for.

-t [type] will list file systems matching filesystem type [type]

-x [type] will list file systems not matching file system type [type]

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

  • What are some more possible values of '[type]'? For example, for the loop devices, e.g. /dev/loop27?

    E.g., df -h -x squashfs -x tmpfs -x devtmpfs will cut down the output to that of earlier times.

  • Or in other words, I suggest extending the answer to be a little bit more generally applicable, for example, including how that '[type]' information can be located. (But ****** ****** without ****** ****** "Edit:", "Update:", or similar - the question/answer should appear as if it was written today.)

  • OK, the OP has left the building: "Last seen more than 6 years ago". Perhaps somebody is willing to do it?
