Zsh 설치 이유

• a shell designed for interactive use, although it is also a powerful scripting language.
• 맥 iTerm, Ubuntu 터미널 앱 같은 환경으로 맞추기 위해 ..

현재 환경

### 현재 Shell 확인
$ echo $0
$ echo $SHELL
/bin/zsh

### 현재 Shell 위치 
$ which zsh                                                                     ✔ │ base 
/bin/zsh

### 버전 확인
$ zsh --version                                                                 ✔ │ base 

Zsh 설정 파일 로딩 순서 

  /etc/zsh/zshenv  –> /etc/zsh/zprofile   –>  /etc/zsh/zshrc    –>  /etc/zsh/zlogin

~/.zshenv  –> ~/.zprofile  –> ~/.zlogin –> ~/.zshrc

.zshenv

Since .zshenv is always sourced, it often contains exported variables that should be available to other programs.
For example, $PATH, $EDITOR, and $PAGER are often set in .zshenv.
Also, you can set $ZDOTDIR in .zshenv to specify an alternative location for the rest of your zsh configuration.

.zshrc

is for interactive shell configuration. You set options for the interactive shell there with the setopt and unsetopt commands. You can also load shell modules, set your history options, change your prompt, set up zle and completion, et cetera. You also set any variables that are only used in the interactive shell (e.g. $LS_COLORS).

.zlogin

is sourced on the start of a login shell. This file is often used to start X using startx.
Some systems start X on boot, so this file is not always very useful.
.zlogin is sourced after .zshrc

.zprofile

is basically the same as .zlogin except that it’s sourced directly before .zshrc is sourced instead of directly after it.
According to the zsh documentation, “.zprofile is meant as an alternative to `.zlogin’ for ksh fans; the two are not intended to be used together, although this could certainly be done if desired.”

.zlogout

is sometimes used to clear and reset the terminal.
You should go through the configuration files of random Github users to get a better idea of what each file should contain.

Themes

https://github.com/robbyrussell/oh-my-zsh/wiki/Themes 에 여러 테마를 고를수 있다. 

Powerlevel10k (Oh My Zsh에 적용 가능한 테마중 하나)

https://github.com/romkatv/powerlevel10k

$ git clone https://github.com/romkatv/powerlevel10k.git ~/powerlevel10k
$ source ~/powerlevel10k/powerlevel10k.zsh-theme
$ p10k configure

잘못 선택했다면 p10k.zsh 라는 파일을 지우면 다시 설정할 수 있게 해준다.

Enabling Plugins

https://github.com/robbyrussell/oh-my-zsh/wiki/Plugins
Plugins을 설치하면서 추가기능 사용 (~/.oh-my-zsh/plugins/*)

vi /.zshrc

plugins=(git sublime)

Using Plugins

Most plugins (should! we’re working on this) include a README, which documents how to use them.

# Code from Mikael Magnusson: http://www.zsh.org/mla/users/2011/msg00367.html
#
# Requires xterm, urxvt, iTerm2 or any other terminal that supports bracketed
# paste mode as documented: http://www.xfree86.org/current/ctlseqs.html

# create a new keymap to use while pasting
bindkey -N paste
# make everything in this keymap call our custom widget

# these are the codes sent around the pasted text in bracketed
# paste mode.
# do the first one with both -M viins and -M vicmd in vi mode
