    sudo !! to rerun last command as sudo.

    history can be paired with !5 to run the fifth command listed in history.

        I believe it’s the fifth oldest - I think !-5 will get you the fifth impost recent, but I was shown that and haven’t put it into practice.

        The most common usecase I do is something like history | grep docker to find docker commands I’ve ran, then use ! followed by the number associated with the command I want to run in history.

      @papertowels@lemmy.one I’ve been working in the bash shell since 1993 and did not know sudo !! was a thing. Good lord, I no longer have to press up, press crtl-left a bunch of times, then type sudo enter space anymore. And I can give it an easy-to-remember alias like ‘resu’ or ‘redo’! Ahahaha, this changes everything! Thank you!!

    I use “ping” every time I suspect my internet might be going a bit slow.

      Try mtr . It’ll run kinda like a trace route but will show you where the delay is happening. Still relys in icmp not being blocked

        ‘mtr’ is not recognized as an internal or external command, operable program or batch file.

        I assume I’m on the wrong OS.

    In my ~/.bashprofile: alias resource="source ~/.bashprofile"

    In my terminal: resource

      omz reload

      not going to say zsh is better than bash or fish, but oh-my-zsh does make it more attractive for some use-cases

          I’ll have to give starship a try, seems like a cool way to handle customizing the prompt

          as to the “omz is bloat and slows down your shell”:

          1. How slow? Because I’ve never noticed. Are we talking about waiting for 15 seconds when I should only have to wait for 1, or are we talking theory and the difference between 0.5 vs 0.08 seconds in benchmarks?

          Because I’ve never been inconvenienced by the speed of my shell nor terminal emulator, despite having tried all kinds of setups. Turns out that “blazing fast” gpu accelerated terminal really didn’t make much of a difference on human timescales. Now I’m at the point where I appreciate the features over the performance.

          1. In reply to Brody’s point, I’m inclined to say “yes, and…?”

          OMZ automates a lot. Sure, I could follow his way of manulaly sourcing dozens of individual shellscripts and making my own aliases and have a zshrc 1200 lines long… Or I could just let omz handle it.

          Yes it’s mostly just a plugin manager, and…? Yes it automates a process I could do manually, and… ? Yes, it uses bindings that I didn’t personally write, and… ?

          Fuck off with the clickbait “You’re living your life wrong, do this lifehack instead!!!” (and the lifehack is to reinvent the wheel) bullshit

          Here’s a fun real lifehack: try things out for yourself, don’t just listen to and parrot other people’s opinions, don’t be afraid to go against the grain. Way more fun and fulfilling that way!

        I would but much like somebody else’s recent post I have in the past nuked my install by blindly agreeing to some recommended software removals before. These days I like to double check what packages are being updated and replaced.
