Do you have experience working with the Linux operating system?

Yes, experience working with the Linux operating system is often necessary in QA and test automation. Linux provides powerful tools for working with files, processes, and networks, as well as a convenient environment for running scripts and automation.

Examples of using Linux in QA:

• Writing and running shell scripts for test automation.
• Using the command line to manage test environments.
• Working with system logs and monitoring.
• Setting up CI/CD pipelines on Linux servers.

Knowledge of basic commands (ls, grep, awk, sed, ps, top), permissions, package management, and file handling is an important part of a QA engineer's skills.
