I didn't see it mentioned, but I use it frequently so here is my tip. I'm not sure if it is bash specific (I just use it!). Instead of typing !$ for the previous command's final argument, you can use the keyboard shortcut alt+. (alt+period). Pressing it multiple times will go to the last argument of previous commands. I use this quite a bit and found it easier than !$, because you can see which command it will be : ) I still don't always understand exactly what is happening with subprocesses vs subshells (chriswarbo's post is very useful in pointing out how wrinkly this can be), so I try and keep bash my usage simple.
