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.
