mountpoint

Mountpoint is a command line tool in Unix-like operating systems that allows users to identify if a given directory is a mountpoint or not. It is commonly used to determine the mountpoint of a mounted file system. When provided with a single argument (a directory path), mountpoint checks if the specified directory is a mountpoint and returns an exit status of 0 if it is, and non-zero if it is not. This tool helps in understanding the file system hierarchy and the mounted file systems within it. It can be utilized to determine if a directory is a mountpoint before performing specific operations to avoid unintentional modifications. Mountpoint is usually included as part of the util-linux package in many Linux distributions.
