$0
In a Unix or Linux shell (like bash, zsh, etc.), $0 has a special meaning — it represents the name of the currently running script or shell.
When you run a script, $0 expands to the name or path of that script.
When you’re typing commands directly in the shell, $0 usually expands to the name of the shell itself (e.g., bash or zsh).

whoami && pwd && ls -la
Since we are already logged in as the Bandit33 user, run the following command to retrieve the flag.
cat /etc/bandit_pass/bandit33
