This course finally made me understand file permissions in Unix. I can now easily read and change permission strings without confusion.

This course improved my confidence as a beginner system administrator. I now understand both security and usability aspects.

The environment variables section was very practical. I learned how to configure and export them for smoother workflows.

The explanation of numeric vs symbolic permissions was very clear. I had always mixed them up before, but not anymore.

The course gave me confidence to manage user and group ownership properly, which is very useful for system security.

I can now set permissions correctly for files and directories and understand the security implications behind them.

The real-life examples of multi-user environments helped me see why permissions matter so much in Unix systems.

The examples were very practical. I immediately applied them in my system and they worked perfectly.

The startup profile lessons were super helpful.
