Setting the Default File System
You can specify the file system or directory that the system uses as the default file system by using the
cd filesystem: privileged EXEC command. You can set the default file system to omit the filesystem:
argument from related commands. For example, for all privileged EXEC commands that have the
optional filesystem: argument, the system uses the file system specified by the cd command.
By default, the default file system is flash:.
You can display the current default file system as specified by the cd command by using the pwd
privileged EXEC command.
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.
