Linux zsh 配置及oh-my-zsh github访问速度慢的应对

• Linux zsh 配置

1. 安装zsh: apt install zsh

2. 安装oh-my-zsh: (摘抄自:https://ohmyz.sh/#install)
   Install oh-my-zsh via curl:
   sh -c “$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)”
   Install oh-my-zsh via wget:
   sh -c “$(wget https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh -O -)”

3. 设置zsh为默认shell: chsh -s /bin/zsh root

• oh-my-zsh github访问速度慢的应对
  oh-my-zsh GitHub库地址.
  git colne 访问网速太差的话, 可以考虑下面三个措施中的一个:
  1. 下载压缩包ohmyzsh.zip,然后手动配置
  2. 访问优快云 Code China 镜像库
  3. 直接运行下面这个脚本也可安装:

#!/bin/sh
#
# This script should be run via curl:
#   sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
# or via wget:
#   sh -c "$(wget -qO- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
# or via fetch:
#   sh -c "$(fetch -o - https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
#
# As an alternative, you can first download the install script and run it afterwards:
#   wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh
#   sh install.sh
#
# You can tweak the install behavior by setting variables when running the script. For
# example, to change the path to the Oh My Zsh repository:
#   ZSH=~/.zsh sh install.sh
#
# Respects the following environment variables:
#   ZSH     - path to the Oh My Zsh repository folder (default: $HOME/.oh-my-zsh)
#   REPO    - name of the GitHub repo to install from (default: ohmyzsh/ohmyzsh)
#   REMOTE  - full remote URL of the git repo to install (default: GitHub via HTTPS)
#   BRANCH  - branch to check out immediately after install (default: master)
#
# Other options:
#   CHSH       - 'no' means the installer will not change the default shell (default: yes)
#   RUNZSH     - 'no' means the installer will not run zsh after the install (default: yes)
#   KEEP_ZSHRC - 'yes' means the installer will not replace an existing .zshrc (default: no)
#
# You can also pass some arguments to the install script to set some these options:
#   --skip-chsh: has the same behavior as setting CHSH to 'no'
#   --unattended: sets both CHSH and RUNZSH to 'no'
#   --keep-zshrc: sets KEEP_ZSHRC to 'yes'
# For example:
#   sh install.sh --unattended
# or:
#   sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)" "" --unattended
#
set -e

# Track if $ZSH was provided
custom_zsh=${ZSH:+yes}

# Default settings
ZSH=${ZSH:-~/.oh-my-zsh}
# REPO=${REPO:-ohmyzsh/ohmyzsh}
REMOTE='https://codechina.youkuaiyun.com/mirrors/ohmyzsh/ohmyzsh.git'
BRANCH=${BRANCH:-master}

# Other options
CHSH=${CHSH:-yes}
RUNZSH=${RUNZSH:-yes}
KEEP_ZSHRC=${KEEP_ZSHRC:-no}
