How to check mounted filesystems and mount options in Linux

See what is mounted, where, and with which options using findmnt, mount, and /etc/fstab.

Check what is currently mounted and how, and what will mount at boot. findmnt is the clearest view; /etc/fstab defines the persistent mounts.

# Readable tree of current mounts
findmnt

# A single mount point
findmnt /u01

# Everything currently mounted, aligned
mount | column -t

# Persistent mounts defined for boot
cat /etc/fstab
