Managing processes and services in Linux

Managing processes and services in Linux involves controlling running applications and system services. Here are some code examples for common process and service management tasks in Linux:

  • Listing running processes

To list the currently running processes in Linux, use the ps command followed by desired options. Here are some examples:

  • List all running processes:

Copy code
ps -ef
  • List all running processes in a tree structure:

    • Copy code
    ps auxf
    • Killing a process

    To terminate a running process in Linux, use the kill command followed by the process ID (PID). Here's an example:

    bash
    Copy code
    kill 1234

    This command will send a SIGTERM signal to the process with PID 1234, asking it to terminate gracefully. If the process does not respond to the SIGTERM signal, you can use the -9 option to send a SIGKILL signal, forcing it to terminate immediately:

    bash
    Copy code
    kill -9 1234
    • Starting and stopping services

    To start and stop system services in Linux, use the systemctl command followed by the desired options. Here are some examples:

    • Start a service:

    sql
    Copy code
    sudo systemctl start service-name
  • Stop a service:

    • vbnet
    Copy code
    sudo systemctl stop service-name
  • Restart a service:

    • Copy code
    sudo systemctl restart service-name
  • Enable a service to start automatically on boot:

    • bash
    Copy code
    sudo systemctl enable service-name
  • Disable a service from starting automatically on boot:

    • bash
    Copy code
    sudo systemctl disable service-name
    • Checking service status

    To check the status of a running service in Linux, use the systemctl status command followed by the service name. Here's an example:

    lua
    Copy code
    sudo systemctl status service-name

    This command will display information about the service, including whether it is running or stopped, and any errors or warnings that may be present.

    These are some examples of basic process and service management tasks in Linux. There are many more advanced options available, such as managing process priority and resource usage, but these commands should be enough to get you started.
