Unix is my IDE

Unix is my IDETomáš Kramár, @tkramar

Integrated DevelopmentEnvironmentThe primary rationale for using an IDEis that it gathers all your tools in thesame place, and you can use them inconcert with roughly the same userinterface paradigm, and withouthaving to exert too much effort to makeseparate applications cooperate.

Using UNIX as IDE● Shell tips● ZSH● Moving around● Terminal multiplexor● Composing commands● Customizing applications

Shell tips

#1 I need to run a longcommand I ran previouslyWrong:● lookup the parameters and type it all again● <up> <up> <up> ....● grep .bash_historyGood:● <c-r>, start typing, <c-r> to scroll results

#2 Oops, I made a typoWrong● <left> <left> <backspace> <backspace> ....Good● <c-u> - deletes from cursor to the beginning● <c-k> - deletes from cursor to the end● <c-w> - deletes word before cursor● <c-a> - move to the beginning● <c-e> - move to the endBetter● use vi-mode

#3 I need to switch to adifferent applicatione.g., I am in vim and want to try something inirbWrong:● open new terminal windowGood● <c-z> to suspend● fg to resume

#4 I need to disconnectfrom remote machineWrong● Ok, Ill waitGood● <c-z> to suspend● bg to run in background● disown to ignore SIGHUP

#5 I forgot sudoWrong● <up> <c-a> sudo <cr>Good● sudo !!● !! is alias for last commandBetter● Custom keybinding that inserts sudo

#6 I want to change thisfiles extensionWrong● cp /opt/nginx/conf/nginx.conf /opt/nginx/conf/nginx.conf.bakGood● cp /opt/nginx/conf/nginx.conf{,.bak}

#7 I want to exit the shellWrong● type exit● click close buttonGood● <c-d>

Keybindings work everywhere (readline).● mysql● psql● irb● ..● even browsers textarea

Features● Autocompletion menu● Autocomplete everything ○ command line parameters ○ remote servers ○ remote filesystems ○ context-sensitive completion (e.g., dvips, git) ○ kill● Fuzzy autocompletion● Globbing ○ ls **/*.txt

Moving around

Stupid tricks● autocomplete● "cd" (no args) back to home● "cd -" back to previous directory

Use the dirstack● dirs -v● pushd/popdOr● setopt auto_pushd● cd +3

Ranger● https://github.com/hut/ranger● OSX Finder w vim keybindings● Integrates with shell easily

Terminal multiplexor

tmux● multiplexes several virtual terminals● sessions/windows● tile management

Composing commands

How do you identify yourlargest files?

How do you identify your largest files?wc -l **/*.rb | tac | tail -n +2 | sort -n -r | head -10

Customizing applications

Embrace aliasesalias grep="grep --color=auto"alias lsa="ls -AahXBFov --color=auto --indicator-style=file-type --group-directories-first"alias pacman="sudo pacman"Application level aliases● git la

dotfiles● Most applications are configurable in plain text ○ .vimrc, .zshrc, .ranger, .rvm, .ssh ... ○ Transfer between machines, backup, restore
