While I prefer EDIT, on MS-DOS, or a very similar editor, Leafpad,
on Linux, you only need to know 6 VI commands and 3 EX/ED commands
to use VI very effectively.  If you use GREP, you probably already
familiar the regular expressions that VI uses.  One of the areas
where VI excels, due to the EX/ED commands, is matching many lines
on a line-by-line basis from a command instead of visually editing,
although it has a visual editing mode too, at least on Linux nowadays.
The line-by-line ability makes VI excellent for processing lists or
word dictionaries or DNS names or Usenet groups list or C program
output or system logs, etc.  The other area where VI excels is that
good ports of it are available on nearly every platform, even
including DOS.  It's probably worth learning just for that.
