Have you heard of the command line tool 'fzf', aka. the Fuzzy Finder. It's an interactive Unix filter for command-line that can be used with any list. It's similar in concept to graphical tools like 'dmenu' or 'rofi' except 'fzf' is a CLI tool.

So cool! I'm glad you saw my question on Mastodon. An important difference with Dmenu or Rofi is you can misspell: fzf can search similar results taking into account interpolations of letters, missing letters, extra letters, etc. That's the "fuzzy" part. Sounds like a detail, but in real life that's what makes it so fast and efficient to use.

@MasterHigure Год назад

At my previous workplace, a colleague installed fzf on one of the remote servers, and I discovered that it made ctrl-r a dream. The history search became a LOT easier. I admit I have no idea how he made the bash history search use fzf rather than the default, but it was wonderful.

@keyboardwarrior6296 Год назад

fzf comes with a few scripts that are included /usr/share/fzf/. You just source them in your bashrc or zshrc.

@keyboardwarrior6296 Год назад

The key-bindings scripts come with three keybindings, also. ctrl-r for history, ctrl-t for files under the current dir, and alt-c to cd into dirs under the current dir.

@samoylov1973 Год назад

Thanks DT! Here are a few aliases that I use with fzf. They might be useful to others. Especially the ones with preview part hf='history -100 |fzf' mpf='cd ~/Videos && mpv "$(fzf)"' pf='fzf --preview='\''bat --color=always --style=plain {}'\'' --bind k:preview-up,j:preview-down' sqf='sqlite3 "$(fzf --prompt "Please select a database: ")"' vf='vim "$(fzf --preview="bat --color=always --style=plain {}" --bind K:preview-up,J:preview-down --prompt "Please select a file to edit: ")"'

@glidersuzuki5572 Год назад

You can turn these into functions which check whether the fzf result is empty or not before executing them. So, you won't open the program, eg :- mpv if no results are chosen

@samoylov1973 Год назад

@@glidersuzuki5572 good point. But these ones are aliases. And "mpf" cds into ~/Videos first. I know there are some videos there. So (only after 'cd' to a folder) second program 'mpv' is started.

@glidersuzuki5572 Год назад

@@samoylov1973 I have the alias for vim. But sometimes I decide I have to do something before editing the file and I press ctrl-c but vim opens anyway

@samoylov1973 Год назад

@@glidersuzuki5572 one possible way out is to press CTRL+Z == sends current process to pause state. You can decide what to do with it later. Either you kill it, bring to foreground with fg, or run in the background with bg. Hope, this helps.

@n0kodoko143 Год назад

Thanks as always, Derek! A couple of thoughts: 1. (Use case between dmenu/rofi vs fzf) - if you work in an environment where other consumers of your scripts don't have the xserver/ xserver programs, fzf of bound to the terminal. 2. I like to use fd or find to get around the issue you experienced where the script only ran in the absolute path. i.e: $ fd . ~/wallpaper/ -e jpg | fzf | xargs Great thing about programming, so many different ways to a solution! Just in case it helps some other viewers (nice touch using sxiv - I think - as a visual filter)

@mjdstratocaster9716 Год назад

fzf man page finder/viewer: apropos -s 1 . | fzf --preview='man {1}' --preview-window=up Scroll with shift-up shift-down fzf package finder/info viewer: pacman -Q | fzf --preview='pacman -Qi {1}' --preview-window=up Can modify for apt, dnf, etc... Can add keybindings to install/remove selected package(s).

@theodorealenas3171 Год назад

fzf project picker, Emacs inspired: cd "$(find ~/projects -name .git -exec basename {} \; | fzf --preview "tree {}")" (This is not how I do it, but it used to be how I did it more or less) fzf git checkout thing for some reason git log --oneline --all --graph | fzf --preview "God knows what" | sed 's/[*/\| ]$\S$.*/\1/' | xargs git checkout I guess. I hope.

@soanvig Год назад

Fzf has some powerful options allowing you to build custom commands with a dedicated menu bar inside fzf effectively turning it into full blown TUI for many programs that may need it

@fanaFSF Год назад

Instead of "command ls" you can do it like this: "\ls"

@DistroTube Год назад

True, but I'm not usually running Bash. Mostly spend my time in Fish and the backslash trick doesn't work there. But 'command' works everywhere. ;)

The wallpaper setter combination could work really cool with feh. I tried some other day to set a very low-res pixel art wallpapers, but nitrogen was incapable of not making an ugly blur of enlarged pixels. Once I learned about feh I was relieved, cos it had a function to remove any ugly blurring from the upscaling. But it was tedious to put all those flags in the feh command... a bash script + fzf could make a usefuyl combination of a pixel-art wallpaper chooser :)

COME ON! --preview is the reason of fzf! It's the reason to replace dmenu with a terminal with fzf in it! It can act like NeoVim telescope, or it can give you the manual of the program you're about to run, or a preview of a file, or stats about a system process..

@terrydaktyllus1320 Год назад

@@dod_ytent9984 "I will use this more than sed/awk for sure." I am just holding up a mirror to your own words - and what concerns me more is if you think sed and awk are "alternatives" to fzf, then you really can't know sed and awk that well in the first place. "fzf" = "fuzzy file finder", it finds files, like "find" does. "sed" and "awk" allow pattern matching and string replacement *INSIDE* files, i.e. once you have found the files. So do you understand now?

@dod_ytent9984 Год назад

@@terrydaktyllus1320 ok, i will try my best to be more clear. I know what sed, awk and fzf do, and i know that each perform separate functions. I meant to say, in my day to day, i need what fzf does more than what sed/awk does, thus i use it more than I do sed/awk. Along with that this was a callback to DT's awk and sed tutorials.

I've just realised how useful fzf actually is.... though vim is still better than emacs!

I've written a "library" in fennel (works for fennel and lua) so that I can use lisp (fennel is lisp that works like lua) to write shell scripts using fzf. I personally prefer Emacs over neovim though but if you are comfortable with lua, that's good

how can you remember these commands if you're not doing system administration everyday?? that's what kept me away from Linux. It's fun when you learn it the first time, but too much knowledge needs to be ingrained and maintained, to do uncommon things. that's why I'm interested in there being a hybrid text-graphical interface, where mouse and keyboard form separate focus cursors. as you type the graphics change to show the content and the options, you can click to add to the text, without losing focus. this would be a new compositor/server based on Wayland and Weston.

@terrydaktyllus1320 Год назад

"how can you remember these commands if you're not doing system administration everyday??" You make notes, read man pages and/or create web bookmarks to the sites or searches that you use regularly. I started with UNIX-like systems 30 years ago and I still do just that, I don't even try to remember everything. Plus you can use shell aliases or "one line shell scripts" to shorten longer commands also. Linux just gives you "a box of tools", you have to learn how to use those tools.
