What are your best Bash productivity tips? I'll start:
1. CTRL+R for reverse search
2. You might know !! for preceding command, especially in combination with sudo. But are you also familiar with !$ and !_ which can both be used as substitute for the preceding command's last argument?

I'll add my fave basic navigation tips to your excellent list:

- CTRL+LEFT or RIGHT to jump a word back/forward ('cause I always make typos halfway through an arcane list of args 😾 ).
- CTRL+a and CTRL+e to jump to start/end.

50 $DEGEN Great tips! Don't use either of these nearly enough. Thanks for sharing! 😻
