Set device by drive letter parameter

[Willtech]

Script can be consolidated by accepting the device letter parameter. eg;

securewipe --drive=b

Although the script would be useful the form of the parameter input would have to be determined. It is possible to prefill for /dev/sdX however, traditionally it is more useful to provide the device name with the parameter as --drive=sdb and this allows for the use as for example sdb1. Then it could be debated whether to provide the complete device path as --drive=/dev/sdb and this allows for overwriting anything on the computer and is not safe

Also this parameter requires a restriction not to run on sda.
