The ls -l output shows the block device file of our USB stick is /dev/sdd1. Lrwxrwxrwx 1 root root 10 Nov 1 18:07 SanDisk_16G ->. Lrwxrwxrwx 1 root root 10 Oct 28 23:47 Backup ->.

Say we plug in a 16GB USB stick that has a single partition, which is formatted in ext4 format with label “ SanDisk_16G“: $ pwd Let’s see an example of how to find the device we’re about to mount. To identify the partition on the USB drive, we can go to /dev/disk/by-label to find the block device by checking the label of the partition. Most modern Linux distributions will populate a /dev/disk/by-label directory by udev rules. To mount a USB drive in Linux, first of all, we have to find out the name of the USB device we want to mount.Īfter we plug in a USB device, the Linux system adds a new block device file into the /dev directory. media/Data/archLinux.iso on /mnt/archIso type udf (ro,relatime,utf8) 3. Let’s see how to get the mounting information only for udf (Universal Disk Format) filesystems: $ mount -t udf However, if we want to check the mounting information of a particular filesystem type, we can make use of the -t type option. The command mount will, by default, report all mounted filesystems, including the virtual ones such as cgroup on /sys/fs.

We’ll cover some commonly used mount options in the following sections. This is the directory the device is mounted to - the root directory in this case. In this case, it’s the first partition on the second hard disk. The device or filesystem name we want to mount.Let’s pick the last output line as an example to understand the information that the mount command gives us: /dev/sdb1 on / type ext4 (rw,noatime,commit=120) dev/sdb1 on / type ext4 (rw,noatime,commit=120) media/Data/archLinux.iso on /mnt/archIso type udf (ro,relatime,utf8) Run on /run type tmpfs (rw,nosuid,nodev,relatime,mode=755)Ĭgroup on /sys/fs/cgroup/rdma type cgroup (rw,nosuid,nodev,noexec,relatime,rdma)

Sys on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)ĭev on /dev type devtmpfs (rw,nosuid,relatime,size=8133056k,nr_inodes=2033264,mode=755) Proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)
