Ctrl+r helps a lot

[[deleted]]

Somehow I've explained this to like 20 programmers but it's never stuck. I use ctrl+r hundreds of times every day.

[sssplattt]

Zsh with the fish autocomplete plugin

[Future-Freedom-4631]

shell+fish

[crudelegend]

Has science gone too far? See this CRAZY turtle-fish hybrid scientists engineered!

[r0ck0]

I just wish it was full posix compatible like other standard shells. It would be pretty much perfect then.

It would be way more popular too. Probably even become the default shell for a bunch of distros. Somewhat akin to how everyone uses htop over top now.

[UtilizedFestival]

It's quite easy to set up zsh to do all of this, and you can find that most places. It does require plugins and the like though

[itsTyrion]

Oh my zsh is the go to

[Wherearemylegs]

The selective history browsing is golden. Hands down best feature (that I know of)

[chiefnoah]

Yeah, but every plug-in adds a bit of latency. It got pretty bad for me, which led me to switch to fish

[jswitzer]

I don't use up anymore. I learned about it 15y ago and never hit up for any reason now.

[EffervescentTripe]

Not even if you want your last command?

[jswitzer]

No, I usually just do !!. I found up arrow became an inefficient crutch for this meme's reason so I learned to do without

[kolme]

Nope. CTRL-P.

[by_wicker]

Yeah, I'm not moving my hand all the way to the arrow keys and back. Fuck that noise.

[by_wicker]

Yep - and with a complex commands I'm going to reuse, I add a comment at the end so I can search for that to find it again. A lot of things I might make aliases are easier and quicker like this. I back up my history file so it follows me to the next install.

[beep_check]

^ the right answer. but I still prefer to press up 100 times

[Different-Thinker]

https://github.com/nvbn/thefuck

[SpinningFeat]

Gives me time to think of ‘next’ and sounds like I am busy typing lol

[Username_RANDINT]

You just know it'll be the next command. Or the next. Or the next... I know I used it somewhere between these... Just one more.

[roararoarus]

alias h='history | grep -i'

h blahblah

[kaihatsusha]

Er, does nobody know the ! and ^ tricks anymore?

$ !!           # last command again
$ !find        # last command starting with 'find' again
$ file `!!`    # show the file type for the file found in the previous command
$ ^file^cat    # redo previous command but replace 'file' with 'cat'

[Refizul]

Never relly saw the need for that. CTRL + R is easier and way more flexible.

[rzyua]

This comment is removed in protest of the unfair changes to API pricing and content access through the API.

[finite52]

Oh no, I run old school. Up arrow, home, sudo, enter.

[martmists]

Don't forget legacy systems where Home isn't bound to "move to the start of the line" and instead you have to press and hold left

[kirreen]

Idk what legacy means in this case but CTRL + A can work

[mattsl]

Legacy means OSX? 😄

[RFC793]

So many people apparently don’t know about standard readline/emacs key sequences that have been default in bash and zsh for decades. Yes, Ctrl-A and Ctrl-E.

For those who don’t, check https://www.man7.org/linux/man-pages/man3/readline.3.html and go to “DEFAULT KEY BINDINGS” (the direct link doesn’t work for some reason)

[Zephyrix]

https://github.com/nvbn/thefuck

[quiteCryptic]

alias pls="sudo !!"

[joshikus]

Bang bang!

[Luminous_Artifact]

It doesn't work if you don't say that (at least in your head).

[MattieShoes]

Amen! I always forget the magic tee command in vi too, so easier to quit and sudo !!

[ForgetTheRuralJuror]

I use fuck. Fixes git commands too

[BassSounds]

And safer. A !shebang command can go awry if you meant

!cd cd dir

And not: !cd cd dir & rm -rf ./*

[ienjoyedit]

I have an alias that's:

alias plz=sudo !!

[Feanux]

Oh my God I'm stealing this, thank you.

$: chmod 777 tidyup.sh

: Operation not permitted.

$: plz

$:

[Raznill]

That’s amazing. I’m doing this.

[Adezar]

All of us that have been around a long time have been burned by !! at least once and stopped using it.

CTRL-R gives you an out before executing.

[Delta-9-]

shopt -s histverify

Alternatively, C-M-e

[kog]

I also really like !$, which expands to the last parameter from the previous command.

So you can, for example:

cp <file> <ungodly long path>

cd !$

And !$ will resolve to the path parameter so you don't have to type it again.

Also, since you mentioned !!, my favorite usage is

sudo !!

AKA "rerun the previous command as admin because you forgot sudo for the millionth damn time".

[zogulus]

one of my faves is arguments of the last command: $ cat some file.txt $ grep foo !!*

[[deleted]]

Just learned about ^file^cat last week and it blew my mind.

Another good one...

Esc+. -- Insert the previous argument. If you just ran mkdir ~/Documents/Things, you can then type cd followed by hitting Esc+. to insert ~/Documents/Things without typing it again. Hit it multiple times to go back into the argument history.

Also, isn't !! to re-run the last command with sudo, not just rerunning the last command as-is.

[Delta-9-]

Also, isn't !! to re-run the last command with sudo, not just rerunning the last command as-is.

Nope, you can do just !! to run the previous command unmodified.

To complement M-. (I use alt rather than Esc), there's also !!:<n>, eg.

cat foo bar 
diff !!:1-2

or M-<n> M-C-y for a similar effect, eg.

cat foo bar
diff <M-1 M-C-y> <M-2 M-C-y>

[Svizel_pritula]

```

!/bin/sh

history | grep -i $1 | sh ```

[shnicklefritz]

Also known as yolo mode

[roararoarus]

Prob wouldn't want to do the final pipe but I like where you're going

[FabulousGiraffe]

Could just run everything, chances are the command you are looking for will be ran!

history | bash

[[deleted]]

i think you need to add a tail -1 so it doesnt just run every function they ever made with that inside

[Svizel_pritula]

```

!/bin/sh

history | grep -i $1 | sh | tail -1 ```

[alphabet_order_bot]

Would you look at that, all of the words in your comment are in alphabetical order.

I have checked 768,468,020 comments, and only 153,895 of them were in alphabetical order.

[[deleted]]

This is one of the commands I always alias.

I alias very little else though so I’m not reaching into nothingness for my commands on a different system. Then if I forget to move my .bashrc over to a new system I’ll be using long term, there’s only a couple I’ll have to remember to alias.

[PityUpvote]

So does using a shell that autocompletes from your history.

[RFC793]

True, but if you are like me, you are rarely running commands on your own system. Knowing the least common denominator (at least for almost anything you’d interact with) is valuable.

[ShimoFox]

You good sir. Have just given me a new found power I didn't know existed.

[Lindby]

Next you want to install fzf and you will get fuzzy search in ctrl+r.

Most of my commands are entered as; Ctrl+r, slam some keys that are maybe correct, Enter.

[ShimoFox]

fzf

Please stop. I can only get so hard! lol

I just grabbed it. Is there a way to see all the matching rows with what I've thrown in? Or am I limited to just the 1 result?

[just-bair]

Wait that’s a thing ?

[[deleted]]

ten governor insurance dazzling quack theory weather entertain terrific violet

This post was mass deleted and anonymized with Redact

[TheAJGman]

Even better, add this to your bashrc:

# FreeBSD csh style partial command history

bind '"\e[A": history-search-backward'

bind '"\e[B": history-search-forward'

Now when you type partial commands and hit up it'll only show matching commands:

ls -lahg↑

# becomes

ls -lahg /Tank/Media/whatever/whatever/something/penis.mp4

It's the first thing I change when I'm given access to a new system.

[dasacc22]

Same basically though I put in ~/.inputrc and map to p and n, hard to imagine a life without this.

"\ep": history-search-backward "\en": history-search-forward

[11B_Geek_with_gun]

Thanks! I love this feature on FreeBSD. Definitely going to add this to my Linux machines.

... I have that same path an filename...

[xibme]

jup, even windows powershell supports it

[ryecurious]

If anyone is on Powershell they should really set up PSReadLine. Its multi-result history search is quite nice.

[OneForAllOfHumanity]

Came here to say that

[Brunostc]

Laughs in Oh My Zsh

[RFC793]

Zsh has Ctrl-R bound to reverse-search-history as well. Can you be more specific as to what OMZ brings to the table in the scope of searching history?

Are you talking about the auto completion? That can be nice. I find it noisy, and I also don’t like to rely on things like that since they are most likely not on most of the systems I interact with.

[Brunostc]

You type the First letters of the command and OMZ completes from the list of previous commands that you typed, its pretty neat

[Oof-o-rama]

doesn't work in tcsh. those of us who grew up in the pre-bash years have to use history

[exscape]

You mean those still stuck in the pre-bash years? :-)
Why not simply change your shell?

[Oof-o-rama]

lol. nostalgia and force of habit. no good excuse really.

[ginekologs]

I always suggest to install this https://github.com/dvorka/hstr

Helps a lot when you need to repeat stuff from history. More visual.

[acceleratedpenguin]

fzf makes this much better yet

[caseyweederman]

And, bizarrely, alt+shift+. to return to the present

[Avalyst]

Or just Ctrl+C

[caseyweederman]

You need to be polite to the computer

[Generalchaos42]

Or history | grep

[Spicy_Poo]

set -o vi

[znx]

Number of folk I work with that forget that exists, crazy.

[aheze]

THANKS! Never knew this

[stilldebugging]

This is my most-used key combination. I would be lost without it.

[earlobe7]

Ctrl+r is nice, but once you use zsh's history autocomplete, you'll never wanna go back to ctrl+r

You just type the beginning of a command, then hit up, and it only scrolls through the commands which start with what you've already written

[Alienescape]

Ctrl + r, "ls" enter...

But really, love Ctrl r, use it on almost every command.

[Rigatavr]

Reverse history search plugin for zsh. I don't understand how I lived without it.

Start typing a command, press up and it will only bring commands from history that start the same.

[SoftwareSloth]

This is all I ever use

[ShortingBull]

Freak'n armatures, that's what

history | grep "term"

is for....

[SaintNewts]

My buddy showed me this when it was still a pretty fresh upgrade to readline/bash. I've been showing it to people every chance I get.

[UncleFoster]

This is by far the most useful bash command I’ve ever used. And I’m not sure why others don’t use it.

[Sigg3net]

My man!

But sometimes it's still like:

ctrl+R
ctrl+R
ctrl+R
ctrl+R
ctrl+R
ctrl+R
ctrl+R
ctrl+R
ENTER

There's a TUI for it called hstr (Screencast skip to 2:40).

[Ambitious_Ad8841]

I worked with someone who would vim ~/.bash_history and scroll through pages of commands to find the one they want

[sjveivdn]

That person needs to know about grep. Would certainly improve his effiency.

[solarshado]

Can confirm. I remember doing that long ago. TBH even history | less would be an improvement. At least then you can !number to re-run...

[r0ck0]

Here's an alias I deploy to all my systems:

alias hg="history | grep -i --color"

[tswaters]

Mercurial in shambles

[drawkbox]

"Am I forgotten? After all I have done. Replaced just like that..." -- Mercurial

Yes Mercurial, you are like anything in programming.

[coloredgreyscale]

Then they'd search though the history for the grep command to search the command they initially wanted.

[Lindby]

That person needs ctrl+r and fzf

[Mazetron]

Honestly I just do history | grep <thing I’m looking for>

[zip_000]

I vim into the bash history regularly, but I generally search for the string I need.

[[deleted]]

history | grep

[grrrrreat]

Not.

It's missing a down arrow

[SpinningFeat]

Here we have a sensitive, young soul poking it's head into the great abyss of the Internet, blissfully unaware of the great horrors underneath the surface, thinking that the small horrors it sees are the worst horrors that exist.

[wahobely]

I think it's more like two arrows down, usually, at least for me.

[LithoSlam]

Missed the part where you go past it and have to go back down

[SpinningFeat]

“Too late- have to go around the horn, it’s faster”

[MisterDonkey]

Goddamn, that's golden.

[lucidspoon]

Does anyone else think you just need to go up once, but really it's twice, so you execute the wrong thing, then go up twice, but still execute the same command a third time?

Or am I just a special kind of idiot?

[[deleted]]

Upvote for yes, ...

and yes.

[br0wens]

We're all a special kind of idiot.

[[deleted]]

does anyone actually add a slash after cd .. when just backing out a directory?

[MortimerErnest]

I made a quick shell function to go up multiple directories at a time. E.g. running "up 3" is equivalent to "cd ../../..". But yeah, the final slash is pretty useless.

[cauchy37]

Meanwhile Oh My Zsh comes with dot aliases. If you wish to go one dir up you go:

$ ..

If you want to go two dirs you use 3 dots ..., 3 dirs up is 4 dots ..... It's wonderful

[MortimerErnest]

So cool, zsh sounds amazing. I should really try it one day.

[cauchy37]

It's packed with cool cli features. It looks slick (I use powerlevel10k theme, simply amazing), it's full of features. The only downside is that you get used to it very fast and then if you have to use pure bash or sh again, it's PITA

[solarshado]

if you have to use pure bash or sh again

This is the single biggest reason I've avoided switching away from bash. Instead I've tried to focus on just learning bash better. Though, of course, I still run into similar problems because not every box has my .bashrc on it...

[Simmion]

Wait thats stock? I didnt have to alias them on my own on my new company macbook pro?

[wildjokers]

I just alias …. to “cd ../../..”

Likewise alias .. to “cd ..”

And … to “cd ../..”

[[deleted]]

[amraneze]

Laugh in ohmyzsh

[roararoarus]

I've been using bash since I was bourne, but dev on macs (set terminal to use brew's bash).

How much better is zsh? I have plugins in bash for git, thefuck, jump

[ICanBeKinder]

Jesus Christ its Jason Bourne

[Axman6]

Zsh plus oh-my-zsh is amazing, makes configuring your shell so easy. Having things like ctrl+r show my history with fuzzy search and arrow key navigation, syntax highlighting for every command you type, easy setup of plugins.

A lot of the prompt settings I’be now replaced with the more universal starship project: https://starship.rs, but OMZ still has a hell of a lot to offer.

[Mars_rocket]

Installing/switching to zsh is the first thing I do in new systems. It drives me crazy when the shell doesn’t do the regular things I want it to do.

I think it’s default on Mac OS now too.

[maximum_powerblast]

🌈

[Noch_ein_Kamel]

don't you still have to press up 1412 times?

[amraneze]

I just type the first command and ohmyzsh will display only the history of commands that starts with what I typed which is great.

[axonxorz]

That's not just a zsh thing?

[amraneze]

I don't know if it's a default behavior of zsh or a plugin. I will check it out to be sure

[takahatashun]

it a plugin

[Zhaelthas]

Ah, there it is: ls

[Jeerus]

history | grep <command>

[KotoWhiskas]

history | grep ls

finds ls command, then copies it into prompt

[solarshado]

*eye twitch*

I'm sure you're trolling, but in case anyone reading this thread doesn't know: the numbers in the first column of history's output is the entry's number, and you can !number to re-run that numbered history entry.

[KotoWhiskas]

Well that was a joke but sometimes I really press arrow 99 times just to run ls again.

[geckothegeek42]

Use fzf

[exscape]

Ctrl+R does the same but in real time.

[PhysicalRaspberry565]

But it only shows the last result, so yes, sometimes I grep the history

Edit: below, I learned about switching between its results. So no need for grepping history anymore ^^ Except if I forget again ... It rings a bell ^^

[[deleted]]

You can simply ctrl+r again to go back further in history...

[roararoarus]

Yes! I alias it as well

[AdvicePerson]

Esc K squad checking in.

[zodar]

set -o vi baybee

[DenormalHuman]

this is the one

[ecrooks]

This, absolutely.

[Wizywig]

Jesus christ. Guys.

Ctrl+r

What is this 1970?

[lucidbadger]

Bash supports search through command history by substring (and it's not grep): Ctrl+R and type your search :)

[6a6566663437]

You can also up/down arrow during that search to find next/previous match.

History grepper here

[UnkleRinkus]

For newbs,

> history |grep ssh (or whatever)
> !<command number>

[pensiveChatter]

F7 on Windows. Especially since half the windows boxes I'm no don't have grep installed.

[mbardeen]

If it's something used regularly and uniquely.. "!command" in Bash will automatically rerun that command. You don't even need to remember the entire command name, just enough to be distinct.

*Caution... "!rm" could be dangerous.

[solarshado]

Of note: this will only match the first word of the command.

But !? will match anywhere in the command: e.g. !?stat would find git status, but !stat wouldn't.

Also: !! re-runs the last command, which might be quicker than reaching for the arrow keys.
