fuser

Introduction​

This cheat sheet provides a quick reference for some common fuser commands and concepts. fuser is a command-line utility used to identify processes that are using specific files or directories on Unix-like operating systems.

fuser Concepts​

Identifying Processes​

fuser helps identify the processes that are accessing or using a file or directory.

  • Display processes using a file:

    fuser file_name

  • Display processes using a directory:

    fuser -m directory_name

Options​

fuser offers various options to customize its behavior.

  • Display the user owning the process:

    fuser -u file_name

  • Kill processes using a file (use with caution):

    fuser -k file_name

Verbose Output​

fuser can provide verbose output with additional information.

  • Display additional information about processes:
    fuser -v file_name

Forceful Termination​

Use caution when using the -k option, as it forcefully terminates processes using a file or directory.

  • Kill processes using a file:

    fuser -k file_name

  • Kill processes using a directory:

    fuser -k -m directory_name

fuser Command-Line​

  • List processes using a specific file:

    fuser /path/to/file

  • List processes using a directory:

    fuser -m /path/to/directory

  • Display the user owning the processes:

    fuser -u /path/to/file

  • Terminate processes using a file (use with caution):

    fuser -k /path/to/file

  • Display additional information about processes:

    fuser -v /path/to/file
