Shell 命令备忘 ¶

zsh 相关 ¶

安装 ¶

• mac 自带
• Linux 使用对应软件包管理器安装 zsh 即可
  • sudo apt install zsh
• 查看 zsh 路径：which zsh
• 更改默认 shell：sudo chsh -s /usr/bin/zsh

主题 ¶

• 安装 oh-my-zsh（四选一）
  • sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"
  • sh -c "$(curl -fsSL https://gitee.com/mirrors/oh-my-zsh/raw/master/tools/install.sh)"
  • sh -c "$(wget https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
  • sh -c "$(wget -O- https://gitee.com/pocmon/mirrors/raw/master/tools/install.sh)"
• 安装 powerlevel10k（p10k）
  • git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k
  • git clone --depth=1 https://gitee.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k
  • 在 ~/.zshrc 中设置 ZSH_THEME 为 "powerlevel10k/powerlevel10k"

插件 ¶

• 自带 git 插件
• zsh-autosuggestions：git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions
• zsh-syntax-highlighting：git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting
• 然后在 ~/.zshrc 中设置 plugins=(git zsh-autosuggestions zsh-syntax-highlighting)

常用 alias ¶

• 修改 vim 至 nvim

  alias vim='/usr/local/bin/nvim'
  alias ovim='/usr/bin/vim'
  

• 用 sharkdp/bat 替代 cat 实现语法高亮

  # (on macOS) brew install bat
  alias cat='bat -pp'
  

  # (on Linux) sudo apt install bat
  alias cat='batcat -pp'
  

• 设置代理与取消代理

  alias proxy="export https_proxy=http://127.0.0.1:7890 http_proxy=http://127.0.0.1:7890 all_proxy=socks5://127.0.0.1:7890"
  alias noproxy="unset https_proxy http_proxy all_proxy"
  

  • orbstack 的虚拟机连接主机的代理：

    alias proxy="export https_proxy=http://host.orb.internal:7890 http_proxy=http://host.orb.internal:7890 all_proxy=socks5://host.orb.internal:7890"
    

• ssh 跳板代理快捷开关

  alias sshproxy="sed -i '' 's/# ProxyCommand ssh jump/ProxyCommand ssh jump/g' ~/.ssh/config"
  alias sshnoproxy="sed -i '' 's/ProxyCommand ssh jump/# ProxyCommand ssh jump/g' ~/.ssh/config"
  

• 测试代理是否生效

  alias google='curl -v -I https://www.google.com/'
  

conda 环境安装 ¶

安装 miniconda：

mkdir -p ~/miniconda
wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh -O ~/miniconda/miniconda.sh
bash ~/miniconda/miniconda.sh -b -u -p ~/miniconda
rm ~/miniconda/miniconda.sh

source ~/miniconda/bin/activate
conda init zsh
# conda init --all 会莫名其妙加其他不存在的 shell 的配置文件，比如创建 fish 的配置之类的

所有可用的平台、架构的安装脚本都在 https://repo.anaconda.com/miniconda/

neovim 配置 ¶

安装 ¶

• macOS：Homebrew 上的是新的，可以直接安装：

  brew install neovim
  

• Linux：debian / ubuntu 的软件包都很老，要从 GitHub 安装：

  wget https://github.com/neovim/neovim/releases/latest/download/nvim-linux64.tar.gz
  tar xzvf nvim-linux64.tar.gz
  cd nvim-linux64
  sudo cp -r bin/nvim /usr/local/bin
  sudo cp -r lib/nvim /usr/local/lib
  sudo cp -r share/nvim /usr/local/share
  

配置 ¶

• 下载配置文件：我的 nvim 配置文件在 TonyCrane/nvim-config

  cd ~/.config
  git clone https://github.com/TonyCrane/nvim-config.git nvim
  

• 安装 packer.nvim：

  git clone --depth 1 https://github.com/wbthomason/packer.nvim\
  ~/.local/share/nvim/site/pack/packer/start/packer.nvim
  

• 打开 nvim 跳过所有报错，执行 :PackerSync 安装插件

简要 vim 配置 ¶

在不想装 nvim 的服务器上临时用 vim 的简单配置：

syntax on
set expandtab
set number
set autoindent
set smartindent
set tabstop=4
set shiftwidth=4
set softtabstop=4
set laststatus=2
set mouse=a
set scrolloff=4
inoremap { {}<ESC>i
inoremap {<CR> {<CR>}<ESC>O
