mount command in Linux is used to mount file systems or storage devices to a specific location in the Linux directory tree. This command is essential for accessing data from external devices or network shares.
The basic syntax for the
mount command is as follows:
mount [options] device directory
device refers to the device or file system that needs to be mounted, and
directory is the location where the device or file system will be mounted.
For example, to mount a USB drive with the device name
/dev/sdb1 to the directory
/mnt/usb, the command would be:
sudo mount /dev/sdb1 /mnt/usb
Once the device is mounted, all the files and directories in the device can be accessed from the mount point
In addition to this basic usage, there are several other options that can be used with the
mount command. These options are listed in the table below.
||Mount all file systems mentioned in
||Specify the file system type of the device to be mounted.|
||Specify mount options for the device.|
||Mount the device in read-only mode.|
||Mount the device in read-write mode.|
||Do not update the
||Mount the device with the label specified.|
||Mount the device with the UUID specified.|
- If you receive an error message such as “mount: /dev/sdb1 already mounted or /mnt/usb busy”, it means that the device is already mounted or the mount point is currently in use. To resolve this issue, unmount the device or use a different mount point.
- If you encounter permission issues while attempting to mount a device, make sure that you have root privileges or use the
sudocommand to run the
- If a device is not automatically detected by the system, use the
lsblkcommand to check if the device is recognized by the system. If it is, try mounting the device manually using the
- It is important to unmount devices before physically removing them from the system. This can be done using the
umountcommand followed by the mount point or device name.
mountcommand can also be used to mount network shares, such as NFS or Samba shares. In this case, the
deviceargument would be the network path to the share, and the
directoryargument would be the mount point in the local file system.
