内网使用ohmyzsh

一、到github上下载ohmyzsh包
如果有同学不知道怎么*，那就到国内的镜像上去下或者clone都可以，下载完了，压缩一下，拷到内网里，内外网总有文件传输的方式，内网最让人烦恼的还是不能连接到互联网。
二、到https://ohmyz.sh/拿到安装文件
$ sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
这段命令是官方提供的下载和安装方式，但是在无耻的美国的技术*下，我们无法访问很多网站，所以我们需要对这个文件进行一些改动，curl命令下载脚本需要*，所以这里我们直接将修改好的放到gitee上，大家酌情使用。
其实只改动了两处地方：
- 注释如下的代码，因为我们已经下载了ohmyzsh了，不用再到github上clone了，因为也连不通
# git clone -c core.eol=lf -c core.autocrlf=false \
# -c fsck.zeroPaddedFilemode=ignore \
# -c fetch.fsck.zeroPaddedFilemode=ignore \
# -c receive.fsck.zeroPaddedFilemode=ignore \
# --depth=1 --branch "$BRANCH" "$REMOTE" "$ZSH" || {
# fmt_error "git clone of oh-my-zsh repo failed"
# exit 1
# }
- 注释如下代码，这段代码的原意是看看~/.oh-my-zsh是否存在，进而判断是否已经安装
# if [ -d "$ZSH" ]; then
# echo "${YELLOW}The \$ZSH folder already exists ($ZSH).${RESET}"
# if [ "$custom_zsh" = yes ]; then
# cat <<EOF
#
#You ran the installer with the \$ZSH setting or the \$ZSH variable is
#exported. You have 3 options:
#
#1. Unset the ZSH variable when calling the installer:
# $(fmt_code "ZSH= sh install.sh")
#2. Install Oh My Zsh to a directory that doesn't exist yet:
# $(fmt_code "ZSH=path/to/new/ohmyzsh/folder sh install.sh")
#3. (Caution) If the folder doesn't contain important information,
# you can just remove it with $(fmt_code "rm -r $ZSH")
#
#EOF
# else
# echo "You'll need to remove it if you want to reinstall."
# fi
# exit 1
# fi
但是其实这里因为我们已经将git库中的文件解压到了~/.oh-my-zsh下，所以这里加校验就走不通了，因为官方逻辑是：
# if [ -d "$ZSH" ]; then
# echo "${YELLOW}The \$ZSH folder already exists ($ZSH).${RESET}"
# if [ "$custom_zsh" = yes ]; then
# cat <<EOF
#
#You ran the installer with the \$ZSH setting or the \$ZSH variable is
#exported. You have 3 options:
#
#1. Unset the ZSH variable when calling the installer:
# $(fmt_code "ZSH= sh install.sh")
#2. Install Oh My Zsh to a directory that doesn't exist yet:
# $(fmt_code "ZSH=path/to/new/ohmyzsh/folder sh install.sh")
#3. (Caution) If the folder doesn't contain important information,
# you can just remove it with $(fmt_code "rm -r $ZSH")
#
#EOF
# else
# echo "You'll need to remove it if you want to reinstall."
# fi
# exit 1
# fi
setup_ohmyzsh
setup_zshrc
setup_shell
也就是先检查是否安装过，再安装。
3. 最后，执行修改好的代码就行了，将如下的代码拷贝到shell文档并执行就行了。
#!/bin/sh
#
# This script should be run via curl:
# sh -c "$(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
#
