Smart shortcuts and articles I miss

More often than not, I read an article that I think, this might be handy one day, discard it, only to find myself three weeks later thinking, what was that one article about shell tricks?

It's a reminder that I need to write down things more often. This article was about terminal shortcuts. Over a lifetime, these shortcuts can save you hours if not days. Here's a couple of my favorites.

(disclaimer: I'm on mac so I'm not sure this works on another OS)

• CTRL + W: it deletes the last word (I used ALT + Backspace for that in the past so this is faster), this also works while typing outside of the terminal.
• CTRL + U: cut out everything from the cursor to the beginning of the line, and then you can use CTRL + Y to paste it later.
• CTRL + A & CTRL + E: go to the start and end of the line.
• cd -: go to the previous directory.
• CTRL + R: reverse incremental search through previous used commands. Press CTRL + R, type a keyword to find commands from your history. Press CTRL + R again to cycle backwards through matches. I used history | grep <keyword> for this in the past.
• sudo !!: you're typing a command but forgot to run sudo. Instead of having to run it again, run sudo !! and the same command will run with sudo.

A couple of others were more advanced that I might circle back to later.
