Appendix B Formatting the Compact Flash Memory Cards
File and Directory Operations
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 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/
1581 drw- 0 Mar 01 1993 23:50:08 test-config
128094208 bytes total (121626624 bytes free)
Router# rmdir flash:/config/test-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/
No files in directory
128094208 bytes total (121630720 bytes free)
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, the router will enter the default home directory, which is flash:/.
The following example shows output 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
• Displaying the contents of the home directory
• Entering the /config directory
• Verifying that you are in the /config directory
• Entering the home directory of a compact Flash memory card in an external slot (slot0:/)
• Verifying that you are in the slot0:/ directory
• Returning to the home directory (flash:/)
• Verifying that you are in the home directory
Router# cd
