I didn't see Ctrl-r, but I've found that to be the most insanely useful shortcut.

Ctrl-r = reverse history search. Type a partial command after Ctrl-r and it'll find the most recent executed command with that substring in it.

Press Ctrl-r again, jump to the next oldest command containing your substring. Did you accidentally press too many Ctrl-r? Press backspace to move forward in history.

Many of the solutions they highlight can actually be solved with this. Surprised that it wasn't included.

My favorite shell trick (not in the link) is this: ~-

Tilde-hyphen expands to the previous directory you were in, and of course "cd -" returns you to your previous directory, so I put them together all the time.

Here's an example workflow (with a fake PS1):

  mac:/Users/me/Projects/my_new_app$ cd ~/.pow

  mac:/Users/me/.pow$ ln -s ~- .

  mac:/Users/me/.pow$ cd -

  mac:/Users/me/Projects/my_new_app$
Now I can continue working on my app.

That's bit of a contrived example above. Here's a more realistic way to do a symlink for pow:

  mac:/Users/me/Projects/my_new_app$ ln -s `pwd` ~/.pow/

I like the commands, especially the ssh one, which I didn't know before and will certainly use in the future.

I also enjoyed the format of the article. A whole dev team each contributing their own piece to a blog post provides a lot of different voices and styles in a concise way.

The command line navigation commands are just what any Emacs user would expect. vi users can set their $EDITOR to 'vi' to get those commands.

What do you mean you've never used Emacs? mumble whippersnappers mumble

Use `set -o vi` to get vi navigation commands on the command line.

EDIT: In bash, that is. It's `bindkey -v` in zsh.

Here is a rule for how to level up your shell/editing game. If you ever touch your arrow keys, you are doing something wrong.

> ctrl + left arrow Moves the cursor to the left by one word > ctrl + right arrow Moves the cursor to the right by one word

Alt + b and Alt + f are also aliases for the same action.
