우분투 초기 세팅

ubuntu 20.04

기본

sudo apt update
sudo apt install build-essential -y
sudo apt install curl vim git net-tools cmake -y
# ubuntu 20.04 에 python3 는 내장되어있으므로 설치하지 않아도 됨

zsh 세팅

sudo apt install zsh
sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
sed 's/ZSH_THEME="robbyrussell"/ZSH_THEME="agnoster"/' ~/.zshrc > .TMP; mv .TMP ~/.zshrc
mkdir utils; cd utils
git clone https://github.com/powerline/fonts.git --depth=1
cd fonts
./install.sh
# 쉘 Preferences 에서 `Noto Mono for Powerline Regular 11` 로 폰트 변경
cd ..; rm -rf fonts

# apt install fonts-powerline <- 이것도 가능한듯
prompt_newline() {
  if [[ -n $CURRENT_BG ]]; then
    echo -n "%{%k%F{$CURRENT_BG}%}$SEGMENT_SEPARATOR
%{%k%F{yellow}%}❯❯"
  else
    echo -n "%{%k%}"
  fi

  echo -n "%{%f%}"
  CURRENT_BG=''
}
sed -i'.bak' 's/%n@%m/%n/' ~/.oh-my-zsh/themes/agnoster.zsh-theme
# agnoster.zsh-theme.bak 백업파일이 생성
sudo apt install zsh-syntax-highlighting
echo source /usr/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh >> ~/.zshrc
vi ~/.zshrc

# 아래의 코드를 추가
if [ -f ~/.bash_aliases ]; then
    . ~/.bash_aliases
fi

echo alias c='clear'\\nalias python='python3' >> ~/.bash_aliases

# 추가 설정
echo \\nalias pkg='/lib/command-not-found' >> ~/.bash_aliases

위의 세팅을 모두 마친 뒤에, ctrl+atl+t 했을 때 bash 가 뜬다면 reboot 을 해주자
