Mount Point

Also known as: mount, mounting

An existing directory where a filesystem is attached to the tree, making its contents appear there. Done with mount.

What Is a Mount Point in Linux?

Mounting connects a filesystem (a partition, USB stick, ISO, or network share) to a directory. After mount /dev/sdb1 /mnt/data, anything under /mnt/data lives on that disk.

Whatever was in the directory before is hidden while something is mounted over it. findmnt shows the current mount tree, and /etc/fstab defines what mounts automatically at boot.

Example

sudo mount /dev/sdb1 /mnt/data
findmnt /mnt/data
