Remove a Directory

To remove a directory from compact flash memory, use the rmdir {flash: slot0:} command. Before you can remove a directory, all files and subdirectories must be removed from the directory.

The following example shows sample output for displaying the contents of an internal compact flash card, then removing the subdirectory named test-config:

Router# dir flash:

Directory of flash:/config/

Remove directory filename [/config/test-config]?

Delete flash:/config/test-config? [confirm]

Removed dir flash:/config/test-config

Router# dir flash:

Directory of flash:/config/

Enter a Directory and Determine Which Directory You Are In

To enter a directory in compact flash memory, use the cd command.

To determine which directory you are in, use the pwd command.

If you enter only cd, you go to the default home directory, which is flash:/.

The following example shows sample output, respectively, for the following actions:

•Entering the home directory of a compact flash memory card in an internal slot (flash:/)

•Verifying that you are in the home directory
