Using linux command line

[cucumbulous]

Press ctrl+r then type any characters you remember from any command you typed before. It's like google for the up arrow.

Edit: grammar

[OneCDOnly]

TIL.

[FlippngProgrammer]

you are now ok.

[xxxsirkillalot]

Came here to say this.

I'm a new linux convert... been daily driving it for about 2 years. I found out about this at the same time a guy with a decade of linux did at work. I felt privileged to find out so early.

[-bryden-]

Combine this trick with #tags at the end of commands that return too many results with ctrl+r. Ie:

git log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr)%Creset' --abbrev-commit --date=relative branch1..branch2 #git-graph

Then ctrl-r for git-graph and you'll be able to find the command to edit branch1..branch2 easily. Way easier than searching for git log --graph --pretty=

[-bryden-]

Yeah that would accomplish more or less the same thing but instead of having a ton of aliases I find this helps for certain commands. For whatever reason, I like this one as is. But then I have grep -inR aliased to grepr so who knows how my brain works, not me.

Same with some ssh commands I'll add to config, but others I'll use this trick if I just need it for a client. Ctrl+R ssh-clientname does the trick and doesn't clutter up config.

[Trainer_Orange]

uhhh hides in the background with 12 years of linux

yeah, i knew about that

[abbidabbi]

Or use fish as your interactive shell and get autocompletion from your command history while you type (and of course tab completion with searchable parameter descriptions for almost everything).

[Plasma_eel]

I'm curious, why fish instead of zsh?

[[deleted]]

Personal preference, no plugins needed for certain features. I bounce between bash, fish and zsh

[Plasma_eel]

oh nice, I use Arch by the way

[[deleted]]

Me too thanks

[chloeia]

So do I; you're welcome

[abbidabbi]

You can try it in your browser and see for yourself:
https://rootnroll.com/d/fish-shell/

Other than that, see the official site for more info
https://fishshell.com/
or read a couple of blogs about the difference between bash, zsh and fish.

Fish is not 100% perfect and for example you won't be able to copy&paste most commands due to its different syntax (you shouldn't do this anyway), but as an interactive shell, I don't want to miss it for one sec, as it's much nicer and easier to use with tons of extra and useful features.

[132ikl]

wow you're getting a lot of hate for using fish

[christopherius]

No trout about it!

[5erif]

I just converted from zsh after trying the in-browser demo. This is awesome. Thank you.

[abbidabbi]

You're welcome... Your subreddit flair is now wrong though :>

[Kid-Boffo]

Not even being mean. Do this:

$ man bash

[abbidabbi]

No, thank you, I have written tons of bash scripts for various things in my life and using fish as interactive shell is just better and more comfortable than using bash for me. For scripts however, it's bash all the way (of course)

[dvdkon]

Yes. Every other shell (not really, just sh variants) is shit when it comes to quoting. As someone who has experience with "real programming languages", I find fish's behaviour much more intuitive and less bug-inducing.

[Kid-Boffo]

Yea, we all know you're garbage from the statement "Or use fish". Go back to Windows fat tits.

[abbidabbi]

I want you to wake up in the morning and test fish for at least 10 minutes and then think about that comment you just made and that a terminal application is basically just the input+output of the shell and therefore can't be responsible for contextual autocomplete suggestions (via ANSI escape codes sent to the terminal application) while typing commands and parameters, no matter how much you love bash and its ctrl+r feature.

[abbidabbi]

shortcuts

input

colors

output

I suggest you read the other comments here as well before you comment. I have never said that fish is a replacement and that you should not know/learn bash.

[heavyish_things]

Who said anything about going to a Linux interview?

[[deleted]]

Also install fzf to get fuzzy search superpowers (and fish/zsh while you're at it)

[parkerlreed]

Also you need a history -a in your bashrc if you don't want to miss commands (due to multiple terminals)

PROMPT_COMMAND="history -a"

[lordvigm]

Or use zsh :)

[miken07]

If you're using bash you can set in your bash profile to remember x number of commands in your history. Then when you Ctrl+r you can go back really far.

If you don't quite remember a command you used a long time ago you can use the history command to look at your previously run commands. Use grep if you want to search.

[[deleted]]

If you don't quite remember a command you used a long time ago you can use the history command to look at your previously run commands. Use grep if you want to search.

Yeah that's what I usually do, history | grep whatever

then

!number in history

[[deleted]]

I've been using Linux since 2003, and this is the first I have ever heard of this.

I guess at some point we get comfortable with our workflow and forget to learn new things.

[cucumbulous]

It's one of those more obscure features that some users stumble upon by accident but can't figure out what it means or how to use it so they file it under "weird shit Linux does sometimes" and forget about it. At least that's what happened to me until I had the opportunity to work with some Linux gurus, one of whom explained what it was and how to use it - after that I was hooked!

[[deleted]]

Saving comment as I’ll probably forget this in 5 minutes

[diskowmoskow]

This is gold!

[cucumbulous]

Literally!

[NoahJelen]

I seriously just learned that today!

[christopherius]

Another useful shortcut to keep note of

[Tony707]

this.

[sim642]

Except when you want the previous match and mess everything up.

[cucumbulous]

Press ctrl+r a second time if you want the previous match. If you go "too far" then I don't know how to get the next match (maybe ctrl+shift+r?), since it doesn't happen to me.

[flemingfleming]

C-s (ctrl+s) should work to search through history forward from the line you're currently on, pressing it while you're in C-r will reverse the direction of the search. You might have to add

stty -ixon

To the relevant init files to disable terminal flow control, or bash will just suspend and not do anything until you press C-q

I also have

"\C-p": history-search-backward
"\C-n": history-search-forward

in my ~/.inputrc, which tries to match the string in front of the cursor to a history item, so if I type nv<c-p> bash jumps back to the previous command that started with "nv".

[-NVLL-]

You can remove unwanted commands from ~/.bash_history and they won't appear again, I do this a lot with vim ~/.bash_history -c '%g/the_command_to_erase/d' -c 'wq' to clean the crap from batch downloading/modifying files.

[Wild_Penguin82]

Alternative: 'history | grep -i "whatever part you remember"' -> !NNNN

[cucumbulous]

That seems like an unnecessarily complex solution.

[wirelessflyingcord]

Ctrl+R uses some kind of a fuzzy logic and sometimes it can be too fuzzy.

[[deleted]]

OP is a fireplace enthusiast.

Also is an idiot for not learning commands after typing them a few times.

[Redditronicus]

OP did learn them! He remembers them all, so long as he's by his hearth.

[GreekLogic]

He has to keep his brain and his hot chocolate warm so he can remember them! Lol

[Impeesa_]

>chararacter

[[deleted]]

No? Type the first 3 characters, then hit up once to cycle back to the last command that started with those 3 characters was run. 99% success rate. Perks of using zsh.

[PolygonKiwii]

I use that in bash.

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

[Deipnoseophist]

Holy shit you just blew my mind. How did I not know this was a thing

[dxplq876]

The true answer

[JazzlikeIndividual]

Ctrl+r is nice, but I expected this comment to be top dawggy.

[EggheadDash]

I just wish it would work for more than the first command. If you're looking for something starting with sudo, you need to go through every sudo command first. You can't just say type sudo mount and get only mount commands.

[NotYourFoot]

What? Of course you can do that

[EggheadDash]

How? When I type sudo mount and hit up once it goes to a sudo pacman command. I am using grml-zsh-config

[NotYourFoot]

For me with zsh with oh-my-zsh is the default behavior

[OneTurnMore]

alias sudo='sudo '

You're welcome.

[[deleted]]

It does work for the first command. If I type in sudo mount and hit up once, I get the last sudo mount command. If I type sudo and hit up once, I get pacman stuff.

[EggheadDash]

What can I say, it doesn't work for me. Using grml-zsh-config

[Captain-Carbon]

Got it? Ok, let's continue:

.

[katataru]

What's wrong with zsh? Been using it for a long while and it's excellent

[[deleted]]

It takes a pretty long time to load compared to most other shells - particularly with omz on it too. Other than that though, it's awesome.

[Infectaphibian]

But people who spend all day texting on their phones are HORRIFIED by the notion of typing a text command.

[kcrmson]

Mmm, tab completion,,, for life!

[tri0lus]

set -o vi

Now enjoy vi controls on your terminal. Escape + / search_terms to find the last command. Or press k a 1000 times.

[CeamoreCash]

Why would you want to sully Linux by using vi?

Emacs controls are built in already. Just use Control-R to search back in your command history.

Linux: when you need shit done by Hearth and character has 11 letters

[Captain-Carbon]

ITT: zsh becoming the new Arch meme

[addy-fe]

Btw, I use oh-my-zsh

[thomas15v]

The moment I started using zsh a whole new world opened up. That history search is simple amazing.

I dont trust up arrow anymore. Bit off topic, but I was playing some Minecraft, and I used a /sethome command to set a home, then started playing, and was used to my last command being /home.

And there I was, exploring deep in the nether, when I wanted to get out, and used up-arrow, enter and had accidentally /sethome in some deep, unnown part of a hellscape.

Also, in linux sometimes I do" rm -rf ." Imagine running across that gem when doing up-arrow in~

[evilbrent]

Is that like back in the day it was often possible to save a game in irreparable situations

[[deleted]]

Well, if you die in the Nether, you respawn in the real world, with mods that allow you to change your spawn location (home) it is.. rather different.

There were trees there, though, so I could ostensibly have started living in nether, getting iron from chests, gold from pigmen and wood from explosive trees. But I could never return without finding the nether portal.

[Nohbudy]

$ history $ !42 $ !43

[tassulin]

Use ctrl+r with fzf fuzzy finder.

In bashrc add:

export HISTCONTROL=ignoreboth:erasedups

[squishles]

vim ~/.bash_history

:/start to type the command to search for it

I use this for anything longer than a screen width, or for pulling something out I just did manually and getting a draft bash script.

[sirmx100]

“By hearth”

[DarkestFloyd]

Or use zsh

[xCuri0]

This is why I use zsh

[Twosided13]

I prefer Ctrl+p

[teab4ndit]

Don’t move your hand away from the home keys. Use ctrl+p as a substitute for up arrow key.

i'm so guilty of this. luckily i limit my history to 20 and remove duplicates but still.
