Here I am going to tell you about mount drive & devices. A feature which windows does it automatically but in the Linux environment you need to do this manually.
Commands to mount drive & devices
The process of mounting is old when the computer were giant size , every time when you insert a hardware you need to tell the system & know about them. Windows assign the Drive letter automatically like C, D, E and so on. The device unplug is also simple in windows.
To mount or unmount a device in the computer is a very basic thing for a system admin. There are many devices which not auto-mounted by themselves. These devices are mounted by admin.
File Structure
As I have told you in the previous articles about the Linux file structure. A device must be mounted in a empty directory that is made for the devices. If you will mount a device in some other directory then it will be unusable for same time.
The file structure has a directory for every case. The directory are to be used for the appropriate method.

Mount Command
To know everything about mount type
mount -h
All the help for the command will be shown.
The basic syntax for the command is
mount -t filesystemtype location
This command will install a filesystem of type t in the location specified. for example
mount -t /dev/cdrom /media
This command will install a cdrom in the location /media.
The option used in the command are
- rw – read/write
- ro – read only
- user – permit any user to mount
- auto/noauto – no automatic mount
- exec/noexec – control the execution of binaries on the mounted device
There are still many options with mount , you can check then by
man mount
Automount with Fstab
Fstab stands for File system table. A configuration file is checked before mounting a device. All the options for mounting are defined in the config file.
You can see the contents of fstab command by this
cat fstab
The filesystem table has 6 columns
- Device – UUID
- Mount point – directory to attach device
- Type – type of filesystem
- Options – rw (read/write), auto, async, suid, etc
- Dump – options for backup
- Pass – When should fsck should check the filesystem.
Umount
Umount command is to unmount a device.
To unmount a device type the command like this
umount <Drive location>
Note : A device will be unmounted if it is not in use otherwise an error message is displayed.
