Mount Command In UNIX

Posted on in Categories last updated April 16, 2010

How do I use the mount command in UNIX to mount my file systems?

The mount command tells the UNIX operating system that a file system is ready to use i.e. mount a file system at a particular point in the system’s file system hierarchy.

Mount Command

The syntax is as follows:

mount /dev/XYZN /mount/point
WARNING! The mount commands require root user privilege or the corresponding fine-grained privilege, unless the file system is defined as “user mountable” in the /etc/fstab file.


Mount /dev/sda5 (Linux partition) in /data directory:

mkdir /data
mount /dev/sda5 /data
df -H
ls /data
cd /data

Mount /dev/aacd0s1g (FreeBSD UNIX partition) in /salesdata directory:

mkdir /salesdata
df -H
mount /dev/aacd0s1g /salesdata
ls /salesdata
cd /salesdata

Mount /dev/dsk/c1t4d0s0 under Solaris UNIX at /data2, enter:

mkdir /data2
mount /dev/dsk/c1t4d0s0 /data2

To remove mount point run:

umount /salesdata

To mount all file systems listed in /etc/fstab, enter:

mount -a

Further readings:

man mount
