TechRepublic File System Video
Posted by: | CommentsThe TechRepublic site is one of the very best on the web for IT resources and an excellent source of learning materials. I came across a nice video presented by Bill Detwiler the other day called 10 Cisco IOS Router file management commands every Cisco admin should know. Most CCNA students I’ve taught in the last few years have experience of managing files and file systems through GUIs. Very few have used DOS or a Unix/Linux command line to do file management tasks and so they can struggle at first with managing files using IOS. The video includes commands such as:

- cd
- copy
- verify
- fsck
The video post also contains a link to a corresponding article by David Davis that covers each of the commands in a little more detail.
