fuser

Display process IDs currently using files or sockets.

• Find which processes are accessing a file or directory:

fuser {path/to/file_or_directory}

• Show more fields (`USER`, `PID`, `ACCESS` and `COMMAND`):

fuser --verbose {path/to/file_or_directory}

• Identify processes using a TCP socket:

fuser --namespace tcp {port}

• Kill all processes accessing a file or directory (sends the `SIGKILL` signal):

fuser --kill {path/to/file_or_directory}

• Find which processes are accessing the filesystem containing a specific file or directory:

fuser --mount {path/to/file_or_directory}
