lslocks is a Linux command that displays information about current file locks held by processes on the local system. It provides a list of file locks and the processes holding them, including the PID, the name of the process, the type of lock, the device and inode number of the locked file, and the path to the locked file. The information provided by lslocks can be useful in diagnosing issues with file locking and determining which processes are holding locks on specific files.
