While DR-DOS supports del and erase as well, it also supports the shorthand form era, which derived from CP/M. In addition to this, the DR-DOS command processor also supports delq/eraq. These are shorthand forms for the del/era/erase command with an assumed /Q parameter (for 'Query') given as well.
The del command can be extremely dangerous, as it removes files in an unabridged way. The command can be used to bypass Windows Resource Protection's policies, and the only restriction of file deletion is ownership. Because of this, this makes the del command malware if used to delete critical system files such as C:\windows\system32.
