What is the function of the mount command in Linux?

In Linux, the mount command is used to attach a filesystem to a specified mount point, allowing the contents of the filesystem to be accessed through that mount point.

Specific functions include:

1. Mounting a new file system: Attaching a new file system (such as a hard drive partition, USB drive, network file system, etc.) to a specified directory in the Linux file system.
2. Mounting an existing file system: It is possible to remount an existing file system onto a different mount point.
3. To view the mounted file systems, you can use the mount command to see the current list of mounted file systems.
4. You can unmount a file system by using the umount command.

In short, the mount command is used to control the mounting and unmounting of file systems in order to access different storage devices and file systems in Linux.
