Have you had practical interactions with the Linux operating system?

Yes, practical interaction with Linux often includes:

• Working with the command line (bash, zsh) for navigation, file management, and processes.
• Using system utilities (ps, top, grep, awk, sed) for monitoring and data processing.
• Managing packages via apt, yum, or other managers.
• Writing scripts in bash or Python for automation tasks.
• Setting permissions and managing users.
• Working with system logs and configuration files.

For example, running a Python script in Linux might look like this:

python3 script.py

Knowledge of Linux is useful for development, deployment, and support of applications, especially in server and cloud environments.
