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
Ctrl R
holy fucking shit 🤌💪🤯❤️💯
- zsh-autosuggestions
history | fzfalias cat="bat --plain --theme=gruvbox-dark"
Aliasing
cator any other ubiquitous shell utility to a replacement is a mistake. Garuda did this, and it was driving me crazy whycatwas giving me errors. Turns out that they had aliasedbattocat, and sincebatis a different program, it didn’t work in exactly the same way, and an update had introduced some unexpected behavior.Drop-in replacements are dumb. Just learn to use a different command.
I think it’s ok to add this in a personal
.zshrc, not on a distro level:If it breaks something - I’d probably know why and can easily fix it by removing alias/calling cat directly.
Also, scripts almost always use bash or sh in shebang, not zsh. So it only triggers if I type
catin terminal.Also, even zsh scripts don’t read your .zshrc by default.
You have to be a linux user to use the console now?
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.
I just use mcfly
Not sure I understand the point of mcfly. zsh and fish have this functionality built in, where pressing Up with a command partially typed will give auto-completions to that partial match.
Yeah. I also use auto-completions for that. McFly does fuzzy finding and because it’s a different separate db, for me it works better across many sessions to find commands I had just recently used in another session.
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.
…until you press up one too many times and enter the same command but with a typo. Again.
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
Been there, done that.
^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.
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.
You saying I can just skip cat in that command and it works?
history | grep 'cat'My output was empty for that command.
Guess why?
Becausehistoryonly gives the last few lines in my system.
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
I’ve probably done that for
lsRelevant xkcd: https://xkcd.com/1168/
tar --helptar -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
You don’t even need the hyphen!
Mind = blown.
Extract a tarball with verbose output from the specified file.
And learn how to use the ‘z’ option
tar - 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.

… 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
