zsh tab completion also looks through history wich is pretty nice.
I wish this wasn’t so painfully true.
In
fish, you can enter part of the command, and then press up to search for it. It’s kinda awesome.yeah I ONLY just recently switched to fish after using zsh and oh my zsh for so long - pretty much since first starting linux cause I once saw someone using it on unixporn and I thought “that’s cool”
when I switched to NixOS zsh with all the plugins was a total slog. switched to fish and it just HAS everything that zsh/oh my zsh and the various plugins had but baked in.
so yeah in Fish it’s just starting to type something and hoping it’s still in the history.
That’s what I do in bash except for pressing up it’s ctrl+r. FZF does the fuzzy finding for me. It’s so convenient.
Featherpad, copy, paste. Extra work, but you get a work log
O(n) access, very efficient.
No, I do not care to share the value of n
https://github.com/atuinsh/atuin is a great tool to manage and search your shell history. I especially enjoy it being able to search commands based on the working directory I was in when I ran them.
It also has more features (which I don’t use) to manage dotfiles and sync shell history across hosts/devices.
I was going to talk about it too ! Even though I’m on fish (which helps a lot with history search) atuin really changed my habits and made my life easier !
The number of people who don’t reverse-I-search is too damn high
It was quite a while before I realised that was possible.
Then not long after starting to use it, that I got fed up and just started opening up the history file and searching in it.why not
history | grep -iand the search term?even if there are several, you can use ! and the command’s line number to run it again
historyis shell dependent.
CTRL+R for those unitiated
reverse-i-search + fzf = <3
I accidentally found out one day that I could use a wildcard operator in the terminal instead of a full file or folder name due to always doing this.
cd Pho* or cd /documents/Pho*
Will for example open my “Photo Examples” folder in the working directory or based on the path
With ZSH there’s something called “path-completion” that makes that even easier.
Say you want to go to “/usr/local/share/fonts” but that’s too much to type out, you can instead type “cd /u/l/s/f” and hit tab. If every path element is unambiguous it will just expand it to “/usr/local/share/fonts”. In this case though, “/u/l/” can expand to “/usr/local” or “/usr/lib” so when you hit tab it moves the cursor to just after the “l” to indicate it needs you to distinguish between “/usr/local/” and “/usr/lib”. If you just type “o” and hit tab again, it will know that there’s only one match for “/usr/lo” and expand that to “/usr/local/” Then there’s only one match for “s” which is “share”, and only one match for “f” which is “fonts”.
That avoids the danger of executing a command with an asterisk wildcard.
works in fish shell as well.

This only works until you grow an addiction to making pho at home and start documenting your progress.
cd “Pho Recipes and Pictures”
You can use
||between two commands as well. If the first command returns exit code != 0, the second command will run.I.e.
which ansible || pip install ansible.Or && for if you only want the second command to run if the first command succeeded.
cd /
sudo rm -rf *
Basically the Linux version of deleting system32 but idk I’m not a super Linux nerd yet.
The fun thing is that you can create a file named “-rf *” and hope an admin tried to delete it!
cat ~/.bash_history | grepUseless use of cat?
Yes, it was meant to be a self deprecating admission that I have used this unnecessarily verbose command.
Ah. Well. I can not be blameless on this. I also probably use cat unnecessarily still. But less so with grep these days. I’m getting better… I swear!
You saying I can just skip cat in that command and it works?
grep ~/.bash_historyHow did I not know this. Thank you!
it’s
grep STRING FILEto be preciseor
awk '/STRING/′ FILEif you prefer that for some reason
history | grep 'cat'My output was empty for that command.
Guess why?
Becausehistoryonly gives the last few lines in my system.
This is why I like atuin, I can just press up and start typing part of the command and it will likely find it in my history.
You could already do that with just “Ctrl-R” but without atuin redrawing your screen.
I write part of the command then ctrl+r. Using FZF mind you. Such a great utility.
I typed it once, I’m not typing it again
history | grep 'gre[p]' | less -SDoes fuck all when you can’t remember even a piece of the command lol
Then how well you know which command it is when scrolling. At that point it’s googleing how do I move a file or whatever your looking for.
That’s when you start spamming Page Up/Down, Home, End, and
/to search withinless. Usually seeing various commands jogs my memory, especially when they aregrepcommands searching for one I use often enough to be useful but infrequently enough to not remember off the top of my head.
This is the answer
You have to be a linux user to use the console now?
Too many people still use Bash.
Too many distributions still ship with Bash.
In the real world, the only thing better than perfect is standardized.
Yeah, true. But, it’s easy to change.
Bash is the Internet Explorer of shells. It’s great for installing a more useful shell.
That’s super unkind and incorrect. IE was a trash software that was widely available because MS was trying to extend their monopoly into new areas.
Even if it’s not your taste, bash is a mature, stable FLOSS package with wide community support. The reason it is so common is due to it’s positive attributes, not because there is a plot to make it the only choice available to you.
Bash might be better than IE. But I think we can agree that it is no longer a good shell.
Its syntax is awful, and lacks many features that other shells have.
It is only so widely used because it is a de facto standard. If bash was created today, barely no one would us it.
What shell do you recommend?
I like zsh, but some people say great things about fish.
My problem with those is bash is always there and just works.
Yes, just like Internet Explorer.
It’s good to know how to do things in bash, since you’re going to encounter it pretty often. But, that doesn’t mean you shouldn’t customize your shell on the machine(s) you use most often. Why stick with the default when there are better options? You’re just hobbling yourself.
That’s not true. Internet Explorer was fucking useless for scripting together things, unlike bash.
Internet Explorer shell expansion always trips me up.
I like zsh on mac because pretty colors
