  • Don't get baited into back-and-forth insults. We are not animals.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn, no politics, no trolling or ragebaiting.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.

    control shift R, then start typing, it will search your bash history

    [–] LobsterDog@frig.social 15 points 2 years ago (1 children)

    Is it not just Ctrl-R or is that platform dependent

    [–] count_duckula@discuss.tchncs.de 6 points 2 years ago (1 children)

    I have always used ctrl-r but I just checked and both work. TIL.

    [–] tsukassa 3 points 2 years ago

    Thanks for clearing up this mystery.

    [–] mrmanager@lemmy.today 12 points 2 years ago (6 children)

    Hmm, normally it's just ctrl - r... Are you sure the shift is needed on your system?

    Now if you had to guess how often I remember that there is a keyboard shortcut that does this, but don't remember what it is, and do remember that I can just press up 30-70 times...

    [–] HorreC@kbin.social 3 points 2 years ago

    you can hit it again after you are dialed in as much as you want and it will keep going back in time with the words you have in there and stuff that matches!

    [–] rikudou@lemmings.world 5 points 2 years ago

    I recommend using mcfly for that, it makes it even better.

    [–] fuckstick@lemmy.world 4 points 2 years ago (1 children)

    This. It took a while for it to sink in but now it’s muscle memory and a huge time saver

    [–] Bipta@kbin.social 3 points 2 years ago* (last edited 2 years ago) (1 children)

    What now? What is r? How does this work?

    [–] fuckstick@lemmy.world 6 points 2 years ago (1 children)

    CTRL+R brings up a prompt and allows you to search through commands you’ve run before. If you’ve run different variations of the command hitting CTRL+R or CTRL+SHIFT+R cycles through commands similar to what you’ve typed out.

    [–] gaiussabinus@lemmy.world 8 points 2 years ago (1 children)

    I'm new to linux and i've been using $history | grep . This information is very useful, thank you.

    [–] fuckstick@lemmy.world 4 points 2 years ago

    Sure thing! There’s lots of ways to do the same things, but either way stops you from hitting the up key a bajillion times

    [–] DontRedditMyLemmy@lemmy.world 3 points 2 years ago (1 children)

    Why r? Maybe if I knew why r, then I wouldn't forget this every 13 seconds...

    [–] danielton@lemmy.world 10 points 2 years ago

    Reverse search

    [–] m15otw@feddit.uk 50 points 2 years ago (7 children)

    Ctrl+R

    Then type any part of the command (filename, search string, etc)

    Ctrl+R again to cycle through the matches.

    (Best feature in bash)

    [–] p0q@sh.itjust.works 12 points 2 years ago (1 children)

    Use fzf for a more visual search.

    [–] LeanFemurs@lemmy.world 5 points 2 years ago

    This is the way.

    [–] brakenium@lemm.ee 8 points 2 years ago (1 children)

    I've been using this for a long time, never knew I could press Ctrl + R again. Thanks!

    [–] wandering_nomad@lemmy.world 8 points 2 years ago

    Ctrl + S to go the other way if you overshoot!

    [–] spoopyking@lemmy.fmhy.ml 6 points 2 years ago (1 children)

    Or history | grep 'command'

    [–] m15otw@feddit.uk 3 points 2 years ago (1 children)

    Can't just hit enter to run the one you want then, though.

    [–] rufus@lemmy.world 7 points 2 years ago

    Type: !1234 ... to run whatever history number of the command.

    This is why I switched to fish; it seems to be much smarter understanding what I want to type.

    [–] amos@lemmy.world 7 points 2 years ago (4 children)

    Yeah it's great how ctrl-r is kinda the default instead of something you have to go out of your way to use. Just start typing a command and the up arrow will only cycle through history that matches what you've typed so far.

    fzf masterrace

    [–] Aceticon@lemmy.world 8 points 2 years ago

    It's like the bus-stop-paradigm: If I wait just a bit longer and it will come. Meanwhile it would've been faster to walk.

    [–] Badland9085@lemm.ee 7 points 2 years ago

    To anyone who uses vim mode, ? lets you search through your stored command history, from normal mode ofc.

    [–] Sketchpad01@lemmy.world 7 points 2 years ago (1 children)

    Using the history command just to find the specific IP I need to ssh to

    It's even faster if you look for it inside .bash_history.

    We will history | grep docker until morale improves

    [–] JasonDJ@vlemmy.net 4 points 2 years ago* (last edited 2 years ago)

    Gah it's all docker container ps -a. OK, fine, history | grep "docker run".

    Next time I'll put a file in the project directory that tells me how I ran it and .gitignore it. I promise. Next time.

    [–] Ephur@lemmy.world 5 points 2 years ago

    I create so many aliases with the notion of how much time I’ll save… never use ‘em. Works out okay though because a much richer history to fzf through

    [–] brutalbeard@geddit.social 4 points 2 years ago

    history | grep {search term}

    [–] konakona@sh.itjust.works 4 points 2 years ago

    "python3 -m http.server"

    [–] MavTheHack@lemmy.fmhy.ml 4 points 2 years ago

    I just use the 'fuck' command after lazily typing letters that somewhat match the command I want to run

    [–] titey@programming.dev 4 points 2 years ago

    This is the way!

    [–] LandedGentryOnlyClub@lemmy.fmhy.ml 3 points 2 years ago

    Yeah but last time I typed it, it worked. Who knows what ridiculous typos I'd make right now?

    [–] desmosthenes@lemmy.world 3 points 2 years ago

    [–] billygoat@lemmy.fmhy.ml 3 points 2 years ago

    I’ve always used set -o vi. Let’s you use vi commands on the bash prompt.
