5.9.3.2. Seeing What is Mounted
5.9.3.2. Seeing What is Mounted In addition to mounting and unmounting disk space, it is possible to see what is mounted. There are several different ways of doing this: Viewing /etc/mtab Viewing /proc/mounts Issuing the df command 5.9.3.2.1. Viewing /etc/mtab The file /etc/mtab is a normal file that is updated by the mount program whenever file systems are mounted or unmounted. Here is a sample /etc/mtab : Note The /etc/mtab file is meant to be used to display the status of currently-mounted file systems only. It should not be manually modified. Each line represents a file system that is currently mounted and contains the following fields (from left to right): The device specification The mount point The file system type Whether the file system is mounted read-only ( ro ) or read-write ( rw ), along with any other mount options Two unused fields with zeros in them (for compatibility with /etc/fstab [24] ) [24] Refer to Section 5.9.5, "Mounting File Systems Automatically with /etc/fstab " for more information.
