delete

To delete a file on a Flash memory device, use the delete command.

delete {bootflash:filename | slot0:filename | volatile:filename}

Syntax Description

bootflash:	Flash image that resides on the supervisor module.
slot0:	Flash image that resides on another module.
volatile:	Flash image that resides on the volatile file system.
filename	The name of the file to be deleted.

Defaults

None

Command Modes

EXEC

Usage Guidelines

When you delete a file, the software marks the file as deleted, but it does not erase the file. This feature allows you to later recover a "deleted" file using the undelete command. You can delete a file up to 15 times.

If you attempt to delete the configuration file or image specified by the CONFIG_FILE or BOOTLDR environment variable, the system prompts you to confirm the deletion. Also, if you attempt to delete the last valid system image specified in the BOOT environment variable, the system prompts you to confirm the deletion.

Examples

The following example deletes the file named test from the Flash card inserted in slot 0:

switch# delete slot0:test 
Delete slot0:test? [confirm]

This example shows how to delete a file from a directory:

switch# delete dns_config.cfg
switch#

This example shows how to delete a file from an external CompactFlash (slot0):

switch# delete slot0:dns_config.cfg
switch#
