2. Be civil

Understand the difference between a joke and an insult.

Do not harrass or attack members of the community for any reason.

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.

These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.

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. Even if you watch it on a Linux machine.

4. No recent reposts

Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.

Please report posts and comments that break these rules!

Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't fork-bomb your computer.

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 1 year ago (1 children)

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

[–] tsukassa@lemmynsfw.com 3 points 1 year ago

Thanks for clearing up this mystery.

[–] mrmanager@lemmy.today 12 points 1 year ago (3 children)

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

[–] lungdart@lemmy.ca 3 points 1 year ago (3 children)

Don't forget fzf. That will really jazz up your history search!

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...

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 49 points 1 year ago (6 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 1 year ago (1 children)

Use fzf for a more visual search.

[–] LeanFemurs@lemmy.world 5 points 1 year ago

This is the way.

[–] brakenium@lemm.ee 8 points 1 year 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 1 year ago

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

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

Or history | grep 'command'

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

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

[–] rufus@lemmy.world 7 points 1 year ago

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

[–] Skyler@kbin.social 7 points 2 years ago (1 children)

This is my approach, and for those who don't know, you can use those line numbers that come back from history to rerun the command. Like if your output is something like this:

$ history | grep tmp
  501  ls /tmp
  502  history | grep tmp

You can run !501 and it will just re-run ls /tmp

up, up, up, up, up, cd .., ah there it is.

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.

[–] tobier@lemmy.world 8 points 1 year ago (3 children)

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

[–] amos@lemmy.world 7 points 1 year 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.

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

[–] Ignacio@kbin.social 7 points 1 year ago (1 children)

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 1 year 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}

[–] MavTheHack@lemmy.fmhy.ml 4 points 1 year 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 1 year ago

This is the way!

[–] konakona@sh.itjust.works 4 points 1 year ago

"python3 -m http.server"

[–] 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.

[–] LandedGentryOnlyClub@lemmy.fmhy.ml 3 points 1 year ago

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