Emacs and Vim

The vim command structure makes it trivial to define transformations on common blocks of text; words, sentences, paragraphs (lines), blocks of code inside {..}, etc. It makes it easy to repeat those commands, by repeating them a fixed number of times, applying them to every instance in the file, or asking for confirmation around each one.

But, most importantly, it means that we can now extract that little bit of text-transforming functionality into a script we can save and bind to a new command (if it's something particularly reusable). This is really what vim is about to me - providing a language to describe text transformations, in the form of sequences of commands. This means that the way I code every day, conveniently saving me a few seconds like you mentioned above, is the same method I use when writing/editing plugins/macros for the editor to do more complicated tasks, like say consistently formatting every line of a log file that begins with [ERROR] and removing all other lines, so we can process it with some other tool.

Sure, you could write a script in [python/perl/ruby/etcetcetc] to do all that just as well, but the point is that Vim provides a nice little domain specific language right at your fingertips, optimized for working with text at a higher level, capable of handling one-off jobs as easily as big jobs over a whole log file or even as a little command to be reused later.

Also read entire exhaustive help at least once so you get the idea of what is available (it can be done in one weekend, don't try to memorize too much just familiarize yourself with content, then later when you wonder how would you do that in Vim you will remember you read something about that once).

Vim has really great indexed help that you can access directly:

:h :h index :h

and there is also grep for help to search entire help for matches

No matter what you do understand that you will get slower before you get faster. At first expect your productivity to go down seriously, because everything will be strange and new. But persist with it and force yourself to use it. Once you get to the nicer bits you probably will not want to go back. After 6 months of regular use, you will not be able to back, every other editor will feel dumb and will frustrate you to no end (be careful when typing email: ESC key dismisses the compose dialog in a lot of email programs without asking you anything :D).

As for UNIX shell and tools, again get a good BASH tutorial book and learn the basics of interactive shell, learn how to do loops, globs etc. The rest is then all about learning individual tools, not shell itself, which is rather small command interpreter. Look in your /usr/bin and /usr/local/bin for commands and read their man pages. Experiment a lot with them and look at examples of creative use of these.

Back in the early 90s I had a year long course in vi (not Vim) but started using Vim on Amiga 500 days, and after 20 years I still come across new commands and ways to do things. This is the beauty of Vim, you grow with it and it never stops to amaze you. But it is a skill that you keep for a lifetime. It's like learning to touch type, you do it once and you type efficiently for the rest of your life. You may get faster or slower at times in your life but you are always faster than hunt and peckers. Same with Vim, dumb editors come and go, but none ever approach the completeness of Vim.
