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!

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.

I’m personlly a zsh+oh-my-zsh person which has the same type of auto complete option.

My only regret is that something broke the thefuck plugin on my pc and now swearing at my screen doesn’t fix my mistakes.

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.

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
