Linux terminal users be like

ctrl + r gang

Holy Crap. I have gotten into the arrow up mode. Then I went to History.

But, but, but ctrl + r. Holy crap.

Thank you kind sir or madam.
- If you enjoy that, then let me introduce you you fzf - a fuzzy finder that has support for replacing ctrl + r in shells with fuzzy matching. Among other uses.
  
  https://github.com/junegunn/fzf#key-bindings-for-command-line
- Man I over use it at work - even when sitting in front of a pwsh prompt
You can also install https://github.com/dvorka/hstr to supercharge your ctrl+r
- I can recommend fzf since it also supports searching the current directory
- This is it, my first saved comment on lemmy
Is there a MacOS versión of this? Asking for a friend.
- It's the same, ctrl + r. It is a bash/shell thing so works on any os that uses bash or similar shells. Note, it is not the command key, but ctrl, unlike a lot of other shortcuts on macos.
Fish gang arise (no need for ctrl+r, just press up)
- And with a fantastic approximation of fzf history searching.

Ctrl R > start typing

You're welcome to have your life changed

What the actual.... Thanks

Bruh. Ctrl-r

For real. Alternatively use alias to reassign a command to something shorter if it's one you're always searching for later. I use 'update' as an alias for 'apt update && apt upgrade -y && apt autoremove && apt autoclean'
you're amazing, this is going to change how I use fish
Very handy, thank you.
Or the history substring search plugin for zsh showing inline history as you type, like fish.

Y'all know about ctrl-r to search history, right? I went for so many years without even thinking to look for something better than up-arrow, so I have to mention it.

Wait until they learn that you can ctrl+u when you mistyped your password in sudo instead of spamming backspace...
- What does that do?
- Bro. You just changed my life and don't even realize it
- I end up hitting Ctrl+u at work all the time and then being disappointed and holding backspace.
- Damn, that really does solve a lot of problems, lol 😂.
history | grep <search term>

Does the job well if the key combo doesn't work.
- Followed by !xxx where xxx is the number of the command to re-run
- This. I didn't know about CTRL+R, but this has been my goto
Good tip!I didn't know about that. I just tried it out and it works pretty well but I worry how long it will take to break the habit of mashing the up arrow all the time since I've been doing it so long. This is clearly better though.

Finally the ls command!

Time to up your game with Ctrl + R reverse search! 🤓

Oh, and Ctrl + Shift + R brings you back in the search, niiiiice.

Thank you kind stranger 👍 ☺️.
- Look up fzf for luxury treatment
Holy hell this is the best thing since tab autocompletion

Up up up up up up up up up oh wait down

you allllways overshoot
- Based

And the command is something like ls -l 👍

I see you and I had the same idea. Ha!
I usually use ls -hal.
- ls -lah is what I do 🙌

ctrl + r then enter phrase

With fzf!
- I haven't been on linux in a while but i remember using a file manager that had fuzzy finder and it was nice. I miss linux actually. oh well!

Ctrl+R together with fzf makes this obsolete

my humble method: history | grep -i searchterm
- Then ![historynumber] to execute it
fzf is pretty cool, but I found its ctrl-r "menu" to be more confusing than the old "one entry at a time" style.

(Ofc could be a configuration thing but I'm somewhat an oldhat when it comes to my terminal habits.)

vim ~/.inputrc
Paste the following:

"\e[A": history-search-backward "\e[B": history-search-forward

Thank me later

Man, I've been on unix systems since, oh, 1994, but I've never messed with my .inputrc ... may need to take the dive....
Ok this is actually great. Is there a way to make it so when you down arrow again it will clear the cmd line (or take it back to the prefix)?

Like "py" -> up -> down -> result is "py"

Currently it would show my last python command (or whatever matches).
I'll be a madlad and thank you right here, right now!
Hey! Sorry just getting into Linux, I love learning about cool ways of doing things more efficiently. What does this do exactly? I've noticed others mentioning CTRL+R and I am not sure what that means either. Thank you!
- Basically, while ctrl+r is nice, this is how I got used to use my system. What this does is enable search for when you press arrow up. If you type nothing then it’s default behavior but if you type “ssh” and then start pressing arrow up it will bring up the previous command that had the word ssh in. It’s worth it for someone who constantly forgets ctrl+r exists

I usually do ctrl+r but with zsh I can type the beginning of the command and press up and it will search that way too.

fish automatically searches as you type, just start typing and press -> when you find the command you need.
- Zsh does the same, though I think you need oh my zsh and a plugin for it.

I feel this in my soul. Or when you realize you're hitting up up up up to find something trivial like ls and it would have been more efficient to just type ls. LOL.

~/.bash_history is where my documentation lives

yeah, the other day i was supposed to remove a restriction from a router that was some custom thing built on a raspberry pi. i logged in, started messing around, trying to figure out the system, and of course i looked at bash_history because why not, i'm unfamiliar with the setup so it seemed like a good place to start. up until i found some commands editing it. so i'm like

$ export HISTFILE=/dev/null # alright, two can play this game

it ended up being a simply cron job that runs a script that starts and stops hostapd every once in a while. i didn't disable the cron job, i just commented out a critical line from the stop script. happy debugging to the sysadmin, lol

Bro, do you even ^R ?

$ ls -la

Fish finally broke me of this habit, and now it's one of the first things I install on any system

Fish? Please enlighten a casual user
- Friendly Interactive SHell. I also use it, and I find some of the extra features delightful. I don't think it's POSIX compliant if you're one of the two dozen people who have to worry about that for your use case.
- You know how we have the bash shell by default on most Linux systems? Well there's also the fish shell you can probably find it in your repo and try it out.
- Fish Shell - Friendly Interactive Shell. It has tons of themes and customizable prompts, but most importantly it scans through your command history and autocompletes previous commands. You can even to back through previous versions of a certain command for example I copy a couple different files a lot so I'll type 'cd' then press up to get to the specific command I need. It'll also autocomplete command names if they're in the path. It's a life changer for sure
One of the top reasons I use fish is that I never learned how to cycle through the results of ctrl+r in bash
another happy fish convert here too!
Yep, me as well ☺️.

Goodbye reddit and thanks for the fish.

No, no, no. You don't just land on the right one. You accidentally go past it and then have to press down once or twice.

ctrl+p gang RISE UP

history | grep term

The command is ls

I have my zsh set up so that I can type in something and press up to search for commands I ran with the the things I typed

MX Linux does the same with bash
MX Linux does the same with bash

Woah. Quality of meme in this site amazes me.

It's more or less like on reddit, but less users.
- *fewer

I've just signed up to this site and I'm being personally attacked already. smh

Ctrl-R

history | grep {some part of command}

Much more useful for going further back, even without grep.

As some one who SSH's from a phone to run Docker containers and will be moving the container volumes to a different location, I thank you for this lovely command.

Control+r.

You're welcome.

Or history | grep {command}

i have a alias for h which is history, then hg which does this and i can search my whole 52 thousand line history file and find anything i've ran

Guilty. Even knowing better ways laziness wins. Skyrim console too.

ah there's my password...

cat .bash_history | grep keyword

But yeah pretty much.

Why not just history | grep keyword then? Works in any directory.
You know you don't actually have to do cat 😂. But yeah, I know, I do it as well 🤣.
Yeah, I grep on history and then !<number> to execute the line I want

This speaks to me more so for SSH, which I guess is the same…. But yah.

I'm not proud to admit how long I spent as a SysAdmin before starting to use ctrl+r and just typing a search term.

Me when configuring a switch.

Since this post triggered hidden gems: ^old^new will substitute old with new from the last command and execute.

no I don't want to write the single word command out again I'd rather go up the history with more keypresses

esc + k for me! (vi for life)

i'm in this photo and i love it

Easier to type history then !xx where xx is the number of record in history.

I'm more of a tcsh user, where by default alt+p will search backwards for a command that starts with the text currently written in the prompt. So, type "vim" followed by alt+p as many times as necessary until I find the exact vim call that I'm looking for (normally followed by an alt+n because I pressed one too many times on p). In bash by default you have ctrl+r followed by the string you're looking for and press ctrl+r until you find the command. I can see online that alt+p is bound by default to non-incremental-reverse-search-history, where I think history-search-backward would be a better match to tcsh's behavior. Currently not at the computer so I can't test it.

macOS terminal users too

I just type "history" to see the last like 20 things I typed in, chances are in that list.

I’ve been using unix for about 20 years (Oracle DBA) and am embarrassed about how few shortcuts I know. I vaguely remember seeing someone use tab to auto fill a command but never remember to find out how.
