My favourite shell trick is to comment my code: $ some_long_command -with -args -easily -forgotten # thatspecialthing ... Some weeks later .. $ CTRL-R .. finds: $ some_long_command -with -args -easily -forgotten # thatspecialthing Need to see all the special things you've done this week/whenever? $ history | grep "\#" ... Makes for a definite return of sanity ..
omg >$ CTRL-R I could kiss you.. this alone is amazing!
If you are feeling brave
> The “Works (Almost) Everywhere” Club > The Backspace Replacements Also known as "emacs editing mode". Funnily enough, what POSIX mandates is the support for "vi editing mode" which, to my knowledge, almost nobody ever uses. But it's there in most shells, and you can enable it with "set -o vi" in e.g. bash.
Stuff like NVM or Oh My ZSH will add a few seconds to your shell startup time.
I'd advise against using sudo !! though since it adds the command to history and then it's very easy to accidentally trigger, running some undesired command as root without any prior confirmation. IMO pressing up, Ctrl-A and typing "sudo " isn't much longer but saves you from running unknown commands as root by accident

Then one day, I was trying to setup MySQL on a personal Linux machine, and it wouldn't let me use my "standard password" for the admin account. I knew I could just use a different one, but I really wanted to know what the problem was. Took a long time, and I don't remember how I figured it out, but I eventually tracked it to the password ending with '!!'.
It took a while to put it together, and I never confirmed with the dns host support it's what fixed the issue but, I changed my password there, tried the transfer again, and it worked without any help from support. I suspect my plaintext password played some part in a script used in the transfer process, and was outputting the previous command in place of the !! I wish I had asked them if that was it, but if it was, they would have to admit to having my plain text password, or lie about it.
Using the terminal becomes much more cozy and comfortable after I activate vim-mode. A mistake 3 words earlier? No problem: 3bcw and I'm good to go. Want to delete the whole thing? Even easier: cc I can even use v to open the command inside a fully-fledged (neo)vim instance for more complex rework. If you use (neo)vim already, this is the best way to go as there are no new shortcuts to learn and memorize.

I've been a (n)vim user for 20+ years now, but I hate vi-mode in the shell. However if I feel that I need to do a complex command, I just do ctrl-x+e to open up in neovim (with EDITOR=nvim set). I find it a good middle ground.
I WANT to love it - and if I was only ever working on one, or a small number of systems that I was the only one working on I’d probably do it. I’m ALL about customizing my environment.
However ssh into various servers through the day (some of which are totally ephemeral), and having to code switch my brain back and forth between vim mode and emacs mode in the shell would just slow me down and be infuriating each time I connect to a new box.

3bcw What is your keyboard layout? This looks like a crime against humanity on a regular qwerty kb.
> cd -: The classic channel-flipper. Perfect for toggling back and forth. And not only cd. Gotta love 'git checkout -'
