mountpoint checks whether a given directory or file is a filesystem mountpoint by examining /proc/self/mountinfo. It is commonly used in shell scripts to verify mount status before performing operations. The command returns exit code 0 if the path is a mountpoint, and exit code 32 if it is not. Exit code 1 indicates usage errors or system failures.
