#Disclaimers

---

The views expressed in this presentation are entirely my own, and show not be construed to be the opinion of any of my employers (past, present, or future).

---

I'm going to show you a bunch of cool interactive tools. I am not advocating that you install all of them on your production systems or that you assume that they are available when writing portable shell scripts.

---

This list of tools is not exhaustive. In many cases, there are other tools that do nearly the same thing. Sometimes I'll just present the one that I learned first. Sometimes I'll present the one that I prefer. Sometimes I might not know about the cool alternatives.

---

I'm still learning. If you know other cool tools, share them with me!

#Philosophy

#What makes tools good?

• speed?
• ease?
• simplicity?
• documentation?
• size?
• bloat?
• portability?
• power?
• flexibility?

#Feedback

• the core of agility

#Tools

#Getting around

#z - jump around

• {ba,z}sh: github.com/rupa/z
• fish: github.com/jethrokuan/z
• 100% shell script
• frecency
• use instead of cd

::: notes

Demo:

z Dow
z vul
z for
z src
kak ~/.local/share/z/data

#Finding stuff

#fzf - fuzzy find

• github.com/junegunn/fzf
• golang
• fuzzy, not regex
• smart case
• use like:
  • find
  • grep
  • decision

::: notes

ps -aef | fzf
systemctl | fzf
dmesg | fzf
Ctrl+R in fish
Ctrl+T in fish
Alt-C in fish

function gc
	set branch (git show-ref --heads | sed -E 's|refs/heads/||' | fzf --with-nth=2 --preview 'git show --color=always {1}' | string split " ")
	git checkout $branch[2]
end

:::

#fd - find

• github.com/sharkdp/fd
• rust
• use instead of find
• heuristics:
  • skip hidden files by default
  • skip ignored files by default
  • smart case
• even without heuristics, speedup 9x+

::: notes

fd uinput /
find / -name '*uinput*'

fd arbor
fd Arbor
find . -iname '*arbor*'
find . -name '*Arbor*'

:::

#ripgrep - grep, but better

• github.com/BurntSushi/ripgrep
• rust
• use instead of grep
• heuristics:
  • recursive file search by default
  • skip hidden files by default
  • skip ignored files by default
  • smart case
• even without heuristics, speedup 4x+

::: notes

rg 'var Version'
grep -r 'var Version' .

rg arbor
rg Arbor

cd ~/Code/builds/linux/
rg const
rg uinput

rg uinput --json

funced rged

:::

#gron - make JSON greppable!

• github.com/tomnomnom/gron
• golang
• use before jq and with rg or fzf
• combines well with yaml2json and similar

::: notes

jq . pull.json
jq . pull.json | fzf --ansi
jq . pull.json | rg login
gron -c pull.json | fzf --ansi
gron pull.json | rg login
gron pull.json | bat -l js

:::

#Looking at things

#exa - ls for humans

• github.com/ogham/exa
• rust
• alias to ls (use instead of)
• same performance, richer info
• check out --git and --tree

::: notes

exa -h
exa -l --git --tree

:::

#bat - cat with wings

• github.com/sharkdp/bat
• rust
• use instead of cat
• syntax highlighting
• pager auto-invocation
• basically, look at stuff
• combines really well with fzf

::: notes

needs no examples of its own, we've used it constantly throughout the other tools

:::

#hexyl - read the matrix

• github.com/sharkdp/hexyl
• rust
• view hex, but colors

::: notes

hexyl (which kak) | less -r

:::

#Fixing UX

#detox

• detox.sourceforge.net
• c
• Fix file names

::: notes

detox -n *

:::

#fish

• github.com/fish-shell/fish-shell
• c++
• fish_update_completions
• funced & funcsave
• location-sensitive completion
• colored feedback for:
  • whether command exists
  • whether path exists
  • VI-line-editing

::: notes

:::

#Automation

#entr - run commands when files change

• eradman.com/entrproject/
• run commands when files change
• watch files listed on stdin

::: notes

bat makefile

:::

#Multitasking

#tmux - terminal multiplexing

• github.com/tmux/tmux
• c
• 1:N terminals
• supports "tabs" (called windows)
• supports "splits" (called panes)
• supports sessions
• super scriptable

::: notes

:::

#Editing

#kakoune - feedback focused editor

• github.com/mawww/kakoune
• c++
• vi-like, but constant feedback
• commands are discoverable
• see before you do
