Find the source device, filesystem type, and mount options for /srv/docs.
Do not change mount state.
Which command is appropriate?
× Incorrect
findmnt TARGET searches the mount table and shows source, filesystem type, options, and related fields in a structured view.
Detailed explanation
Incorrect
mount -o remount /srv/docsIncorrect. remount changes the existing mount configuration.
Correct
findmnt /srv/docsCorrect. findmnt /srv/docs displays the mount metadata.
Incorrect
umount /srv/docsIncorrect. umount detaches the filesystem.
Incorrect
mkfs /srv/docsIncorrect. mkfs creates a filesystem rather than inspecting a mount.

findmnt inspects state; remount, umount, and mkfs change state or contents.
