- I really like this comic. Just in case someone didn't know in Linux you can:
  
  -Ctrl + r to search previous commands
  
  Or
  
  -type history and precede the command number by an exclamation (!) to repeat the command (I.e. "!13")
  
  Or just !! for the last command. Particularly helpful if you forgot to prefix it with sudo you can run sudo !!
  
  I highly recommend installing fzf, and its shell integration. Makes your Ctrl + r magnitudes more pleasant to use!
  
  What. Da fuck. This always existed?!
  
  Also if you put "sensitive" information in your history by mistake you can use "history -d <line#>" to remove it.
  
  Unfortunately I had to use this command too many times.
  
  Fish shell does this automatically. It's one of the reasons I love it. You can auto-complete based on your command history.
  
  Or control R, start typing a bit, control r again.
  
  This works in Powershell as well, even on Windows...
  
  Ctrl + r to search previous commands
  
  That's a readline thing by the way, so it doesn't just work in bash but also works with other cli applications that are compiled with readline support, for example virsh, psql, fdisk, ...
There is an advantage to this approach though: fewer errors. You're plucking a known working command from a list instead of manually typing a (possibly) broken version of it. Worse yet is when it's a command where typematic mistakes cause unintended side effects like data loss. So, mashing up 100 times can be pretty smart, especially if you're not a great typist.
- @dejected_warp_core That is true if you assume your history contains only working commands...
  
  Oh no, I have to press up 200+ times if we're counting all the detritus and failure in my command history.
Sorry, do you not keep sql scratch files around?

If deving on the cli name and save to separate files your reusable queries...
I've been using Atuin on my work computer and found it to be pretty good if you want something a bit fancier than Ctrl + R
I definitely do this with terminal commands, because I'm not hunting for whatever the specific command line to animate my gif wallpaper is.
- Ctrl + R is a life changer.
  
  HOLY SHIT.
  
  hahahaha, thank you. oh my gosh.
  
  This is the most significant terminal hotkey I've learned in months.

- been there, done that.
  
  then i heard about cli snippet manager. now i use qownnotes snippet manager qc. or you might try pet.
  
  did you know about the ctrl+r command so you can search logged commands by keyword!
  
  magic lobster party told me about it and it's amazing!
  
  I had no idea that was a function until now.
Can’t find the info atm but if you setup inputrc to use vim controls you can use the vim search in psql.
Me looking for apt update && apt upgrade -y
So...Emacs huh
I do that sometimes, lazy as I can be
At work, was recently working on a script that alters the repo significantly. Every time I tested the script, I used the up arrow to get the git clean and git checkout HEAD -- files commands to reset the repo. I must've used those 100+ times.
oh the days before fzf
I open the text file where my powershell history is stored when the command I want isn't recent enough.
That's when I realise I need more coffee.
