What are some common mistakes in shell scripting?
Some common mistakes include not quoting variables, using the wrong shebang, and forgetting to check exit statuses.
Can you explain why quoting variables is important?
Quoting variables prevents word splitting and globbing, which can lead to unexpected behavior in your scripts.
What is the correct way to check exit statuses?
You can check the exit status using the special variable $? right after a command. A status of 0 means success.
Are there any tools to help debug shell scripts?
Yes, tools like shellcheck can analyze your scripts for common errors and provide suggestions for improvement.
