I’ve been using
ctrl + Rmore now :3… though I definitely used to ↑↑↑↑↑↑↑check out fzf (install fzf and add (assuming bash)
eval "$(fzf --bash)"to your .bashrc) Makes ctrl+r a superpowerIt’s awesome until you want to put the cursor in a specific spot of a previous command.
$ rm -f delete-me.txt ctrl-r "me", ctrl-b, ctrl-k $ rm -f deleteBut I still use fzf because while I used to do the above, fzf offered more advantage that made switching worth it.
I’ll try it if I don’t forget it by the next time I have access to my PC lol :3
Ctrl + r with fzf and you’ll never go back.
Woah Ctrl R looks super cool, never knew that I could do that before…
…until you press up one too many times and enter the same command but with a typo. Again.
Been there, done that.
There is an option you can set in .zshrc or .bashrc which only includes lines that exit 0 (success)
Infuriatingly that would omit things like unit test runners from the history in case they don’t pass. As a developer I tend to re-run failed commands quite often, not sure how widely that applies, though.
Oh, stuff like
git diffandgit logwill end up being omitted pretty often.
And a lot of times, the commands that end with piping intoless
Ctrl R
holy fucking shit 🤌💪🤯❤️💯
The number of people who don’t reverse-I-search is too damn high
CTRL+R for those unitiated
reverse-i-search + fzf = <3
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.
^r
and whenever you forget to sudo:
sudo !!You need this: https://github.com/nvbn/thefuck
Ctrl-r, l ctrl-r, ctrl-r, ctrl-r, ctrl-r, ctrl-r, ctrl-r, ctrl-r, ctrl-r. To get ls.
No way! I didn’t know you could cycle through the results like that… awesome!
It’s basically emacs incremental search.
I’ve probably done that for
lstaptaptaptap… taptaptaptap… taptaptaptap taptaptaptap taptaptaptap
… taptaptaptap
… tap …
… shit I was on a different user when I typed it.
Or “shit, I did in tmux last time so I could close the terminal window.”
O(n) access, very efficient.
No, I do not care to share the value of n
Relevant xkcd: https://xkcd.com/1168/
tar -xvf <archive-name>
but only because I had to look it up twice so now my brain has committed it to memory
I don’t even know what it doesi just use unar (unarchive) nowadays, since that works with all file formats iirc
Extract a tarball with verbose output from the specified file.
And learn how to use the ‘z’ option
You don’t even need the hyphen!
Mind = blown.
tar --helptar - h
Unfortunately that’s not valid.
$ tar -h tar: You must specify one of the '-Acdtrux', '--delete' or '--test-label' options Try 'tar --help' or 'tar --usage' for more information.From man-page:
-h, --dereference follow symlinks; archive and dump the files they point toDamn.
Thanks, we all died.
:)
tar -jcvf archive.tbz ~/stuff/*
Of course I don’t know the bomb had bzip2 on it… I wonder if we can start with ls to see if there’s anything to tar or untar
Or, just type the command “history”, find the index number of the desired command, then type “! <index number>”, then <enter>.
That’s way more mental effort than pressing up a bunch of times.
or Ctrl+R then search? I don’t know why some people still bother with
historytbh.Because you can pipe history to grep.
with fzf you get better grep with fuzzy search
This is going to save me so much time pressing the up arrow.
Holy cow!! I didn’t know that. I have been using history > history.txt to find “that one command for that one thing” I only need once every other month or so. Thanks, now I can just do that.
Ctrl-R if you know part of the command.
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 !
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.
Substring completion on ZSH. Type in a small part of the command you want to find and then press up.
bash supports this feature too btw
Added to my mental toolbox, thanks!
I typed it once, I’m not typing it again
also when they see this post
