Linux has a number of editors. See the VI notes and your Unix text for a more complete listing of the VI commands. Unix and Linux are largely the same under terminal emulation. Your editor of choice would normally be used to create your data files as well. Click on this to view the contents of the hard drive.
Some machines also display a ZIP icon.
These disks must also be mounted and unmounted. If you wish to use the hard drive, I suggest you first create a folder for yourself. Linux and Unix always have a working directory that is tied to a location in the file system. Without a leading slash, as in the left command, Linux assumes a subdirectory of the current directory. These are basically the same as the Unix commands.
