Linux Basics courses can help you learn command line navigation, file management, user permissions, and process management. You can build skills in shell scripting, system monitoring, and troubleshooting common issues. Many courses introduce tools like the Bash shell, Git for version control, and text editors such as Vim or Nano, showing how these skills are applied in real-world environments to manage servers and automate tasks.
