Working with the Flash File System
Displaying Information About Files on a File System
You can view a list of the contents of a file system before manipulating its contents. For example, before
copying a new configuration file to Flash memory, you might want to verify that the file system does not
already contain a configuration file with the same name. Similarly, before copying a Flash configuration
file to another location, you might want to verify its filename for use in another command.
To display information about files on a file system, use one of the privileged EXEC commands in
Table 20-2.
Changing Directories and Displaying the Working Directory
Beginning in privileged EXEC mode, follow these steps to change directories and display the working
directory.
