How do you use the linux mount command?

In Linux, the mount command is used to attach a file system to a designated mount point. Its basic usage is as follows:

mount [options] device directory

device represents the device to be mounted (such as a hard drive partition, optical disc, network share, etc.), while directory represents the directory to be mounted to.

Commonly used mount options include:

1. -T: specify the type of file system.
2. -o: specify mounting options (such as ro for read-only, rw for read-write)
3. -Do not write mount information to the /etc/mtab file.
4. Mount all filesystems listed in /etc/fstab.

For example, to mount the hard drive partition named /dev/sdb1 to the directory /mnt/data, you can use the following command:

mount /dev/sdb1 /mnt/data

To specify the file system type as ext4, you can use the following command:

mount -t ext4 /dev/sdb1 /mnt/data
