If you run into a system problem and Linux refuses to boot from the hard disk, for example, you may need to boot from a floppy. In this case, you must edit system files by using the ed editor, because that editor is small enough to fit on the floppy. Although ed and vi may seem more cryptic than other, more graphical text editors, you should learn the basic editing commands of these two editors, because at times, these editors may be the only ones available.
As vi edits a file, it reads the file into a buffer—a block of memory—and enables you to change the text in the buffer. As does the ed editor, vi works with a buffer. The vi editor also uses temporary files during editing, but it doesn’t alter the original file until you save the changes by using the :w command.

Only one can be an active Clearcase server at any given time. I have a script for each Clearcase server. This script activates a single server. Note the file system NFS mount should be in effect. It is not a problem to mount all the NFS servers at once.
