Purpose
Enables privileged EXEC mode.
• Enter your password if prompted.
Deletes the specified configuration file on the specified
flash device.
Note On Class A and B Flash file systems, when you
delete a specific file in flash memory, the system
marks the file as deleted, allowing you to later
recover a deleted file using the undelete EXEC
command. Erased files cannot be recovered. To
permanently erase the configuration file, use the
squeeze EXEC command. On Class C Flash file
systems, you cannot recover a file that has been
deleted. If you attempt to erase or delete the
configuration file specified by the
CONFIG_FILE environment variable, the system
prompts you to confirm the deletion.
