# Sudo-Dev helpers

These are small, read-only shell helpers for maintenance that otherwise turns into another investigation.

They do not change system state. Run them from a terminal, inspect the output, and redact private hostnames or addresses before sharing a transcript.

```bash
./system-inventory.sh
./network-check.sh sudo-dev.com
./listeners.sh
./recent-errors.sh
```

`network-check.sh` accepts a hostname or IPv4 address and defaults to `sudo-dev.com`. They are plain Bash and use tools normally present on macOS or Linux. Missing tools are reported instead of being installed automatically.
