Module 10 · Chapter 9: The terminal without fear
The terminal without fear
In short
Know your folder and machine first. Read output from the first error. Exit code 0 does not always mean the result is right, so check the result. Commands that delete, force or switch off security checks are read before they run.
After this lesson you can
- Run basic terminal commands and read their output
- Understand exit codes and why green does not always mean success
- Recognise dangerous commands before running them
