Have you ever had to execute Linux commands? Which ones do you use?

Yes, I regularly use Linux commands when developing and debugging applications in Go. Some frequently used commands include:

• ps, top — for process monitoring.
• netstat, ss — for checking network connections.
• grep, awk, sed — for filtering and processing logs.
• curl, wget — for testing HTTP requests.
• strace — for tracing system calls.
• docker — for managing containers.

Example: to find all errors in application logs, you can use:

cat app.log | grep ERROR

Or to check which ports the application is listening on:

ss -tuln | grep 8080
