# sdm Image and Disk management commands

sdm has several simple convenience commands to assist with managing a RasPiOS IMG or burned disk. Every one of these commands complete tasks that can of course be done other ways, but are included for their ease of use.

The command format is:
```
sdm <command> /path/to/img [arg1] [arg2]
```
