(or erase

, cmd.exe
, 4DOS, NDOS, 4OS2, 4NT and Windows PowerShell. It is used to delete one or more files or directories from a file system.

Implementations
editThe command is available for various operating systems including DOS, Microware OS-9,[1] IBM OS/2,[2] Microsoft Windows[3] and ReactOS.[4] It is analogous to the Unix rm
command and to the Stratus OpenVOS delete_file
and delete_dir
commands.[5]
DEC RT-11,[6] OS/8,[7] RSX-11,[8] and OpenVMS[9] also provide the delete
command which can be contracted to del
. AmigaDOS[10] and TSC FLEX[11] provide a delete
command as well.
The erase
command is supported by Tim Paterson's SCP 86-DOS.[12] On MS-DOS, the command is available in versions 1 and later.[13] It is also available in the open-source MS-DOS emulator DOSBox.
Datalight ROM-DOS also includes an implementation of the del
and erase
commands.[14]
While Digital Research 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.[15]
THEOS/OASIS[16] and FlexOS[17] provide only the erase
command.
In PowerShell, del
and erase
are predefined command aliases for the Remove-Item
cmdlet which basically serves the same purpose.
Syntax
