Linux commands courses can help you learn file management, system navigation, process control, and user permissions. You can build skills in scripting with Bash, automating tasks, and managing software packages. Many courses introduce tools like the command line interface, text editors such as Vim or Nano, and version control systems like Git, showing how these skills are applied in practical work, from server management to software development.
