Subject: [PATCH] Add check-dummy.sh script

Added a new bash script that always returns OK. The script has usage instructions and exit codes. It also uses getopt to parse arguments.

Significant changes:
- Added check-dummy.sh
- Script always returns OK
- Usage instructions added
- Exit codes defined
- Getopt used for argument parsing
