Implementations

[edit]

The command is available for variousoperating systems includingDOS,MicrowareOS-9,[1]IBMOS/2,[2]MicrosoftWindows[3] andReactOS.[4] It is analogous to theUnixrm command and to theStratusOpenVOSdelete_file anddelete_dircommands.[5]

DECRT-11,[6]OS/8,[7]RSX-11,[8] andOpenVMS[9] also provide thedelete command which can be contracted todel.AmigaDOS[10] andTSCFLEX[11] provide adelete command as well.

Theerase command is supported byTim Paterson'sSCP86-DOS.[12] OnMS-DOS, the command is available in versions 1 and later.[13] It is also available in theopen-source MS-DOSemulatorDOSBox.

DatalightROM-DOS also includes an implementation of thedel anderase commands.[14]

WhileDigital ResearchDR-DOS supportsdel anderase as well, it also supports the shorthand formera, which derived fromCP/M. In addition to this, the DR-DOS command processor also supportsdelq/eraq. These are shorthand forms for thedel/era/erase command with an assumed/Q parameter (for 'Query') given as well.[15]

THEOS/OASIS[16] andFlexOS[17] provide only theerase command.

InPowerShell,del anderase are predefinedcommand aliases for theRemove-Itemcmdlet which basically serves the same purpose.
