oh my zsh安装过程、还原和安装失败的问题解决
oh my zsh
shell的类型有很多种，linux下默认的是bash，虽然bash的功能已经很强大，但对于以懒惰为美德的程序员来说，bash的提示功能不够强大，界面也不够炫，并非理想工具。
而zsh的功能极其强大，只是配置过于复杂，起初只有极客才在用。后来，有个穷极无聊的程序员可能是实在看不下去广大猿友一直只能使用单调的bash, 于是他创建了一个名为oh-my-zsh的开源项目...
自此，只需要简单的安装配置，小白程序员们都可以用上高档大气上档次，狂拽炫酷吊炸天的oh my zsh
安装zsh
以ubuntu 16.04为例：
查看系统当前使用的shell
$ echo $SHELL /bin/bash
查看系统是否安装了zsh
$ cat /etc/shells /bin/sh/bin/bash/sbin/nologin/usr/bin/sh/usr/bin/bash/usr/sbin/nologin/bin/tcsh/bin/csh
ubuntu 16.04默认情况下没安装zsh
用yum安装zsh
$ yum -y install zsh
查看shell列表
$ cat /etc/shells /bin/sh/bin/bash/sbin/nologin/usr/bin/sh/usr/bin/bash/usr/sbin/nologin/bin/tcsh/bin/csh/bin/zsh
切换shell为zsh
$ chsh -s /bin/zshChanging shell for root.Shell changed.
重启服务器后，可使用reboot
重启后，查看当前shell
$ echo $SHELL /bin/zsh
安装 oh my zsh
oh-my-zsh源码是放在github上，先确保你的机器上已安装了git
安装：
wget https://github.com/robbyrussell/oh-my-zsh/raw/master/tools/install.sh -O - | sh
成功界面：

接下来只需简单的配置，就可以享受oh-my-zsh的强大
主题选择
oh-my-zsh有很多漂亮的主题:
我使用的主题是ys
http://blog.ysmood.org/my-ys-terminal-theme/
修改主题：
$ vim ~/.zshrc
将ZSH_THEME改成ys
ZSH_THEME="ys"
更新配置：
$ source ~/.zshrc
自动补齐插件
linux不少命令的参数很多，不可能一一记住，常规的查看手册又觉得慢。如果你也有这种苦恼，那么我相信你会爱上oh-my-zsh的
一图胜千言
下载此插件：
$ wget http://mimosa-pudica.net/src/incr-0.2.zsh
将此插件放到oh-my-zsh目录的插件库下：
# root @ linux in ~/.oh-my-zsh/plugins/incr on git:master x [15:05:07] $ ls root@linuxincr-0.2.zsh
在~/.zshrc文件末尾加上
source ~/.oh-my-zsh/plugins/incr/incr*.zsh
更新配置：
$ source ~/.zshrc
接下来你就可以体验到Your terminal never felt this good before...
与vim的提示相冲突的解决方案
使用自动补全插件可能会与vim的提示功能相冲突，如会报以下错误：
$ vim t_arguments:451: _vim_files: function definition file not found
解决方法：将~/.zcompdump*删除即可
$ rm -rf ~/.zcompdump*$ exec zsh这时你需要安装：# sudo apt-get install libssl-dev当wget出现Can’t connect to HTTPS URL because the SSL module is not available 你需要安装：# sudo apt-get install openssl正在解析主机 raw.githubusercontent.com (raw.githubusercontent.com)... 0.0.0.0正在连接 raw.githubusercontent.com (raw.githubusercontent.com)|0.0.0.0|:443... 失败：解决办法原因就是https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh这个网站是被墙的。开一个梯子，打开https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh保存此脚本到本机。执行sudo sh ./install.sh,看到如下界面表示安装成功了。闲麻烦不想配置hosts，也可以直接执行下面这些命令，把这些命令拷贝到sh文件然后执行即可。这些命令就是https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh里面的命令，拷贝出来方便以后使用#!/bin/shset -eZSH=${ZSH:-~/.oh-my-zsh}REPO=${REPO:-ohmyzsh/ohmyzsh}REMOTE=${REMOTE:-https://github.com/${REPO}.git}BRANCH=${BRANCH:-master}CHSH=${CHSH:-yes}RUNZSH=${RUNZSH:-yes}KEEP_ZSHRC=${KEEP_ZSHRC:-no}command_exists() { command -v "$@" >/dev/null 2>&1}error() { echo ${RED}"Error: $@"${RESET} >&2}setup_color() { if [ -t 1 ]; then RED=$(printf '\033[31m') GREEN=$(printf '\033[32m') YELLOW=$(printf '\033[33m') BLUE=$(printf '\033[34m') BOLD=$(printf '\033[1m') RESET=$(printf '\033[m') else RED="" GREEN="" YELLOW="" BLUE="" BOLD="" RESET="" fi}setup_ohmyzsh() { umask g-w,o-w echo "${BLUE}Cloning Oh My Zsh...${RESET}" command_exists git || { error "git is not installed" exit 1 } if [ "$OSTYPE" = cygwin ] && git --version | grep -q msysgit; then error "Windows/MSYS Git is not supported on Cygwin" error "Make sure the Cygwin git package is installed and is first on the \$PATH" exit 1 fi git clone -c core.eol=lf -c core.autocrlf=false -c fsck.zeroPaddedFilemode=ignore -c fetch.fsck.zeroPaddedFilemode=ignore -c receive.fsck.zeroPaddedFilemode=ignore --depth=1 --branch "$BRANCH" "$REMOTE" "$ZSH" || { error "git clone of oh-my-zsh repo failed" exit 1 } echo}setup_zshrc() { echo "${BLUE}Looking for an existing zsh config...${RESET}" OLD_ZSHRC=~/.zshrc.pre-oh-my-zsh if [ -f ~/.zshrc ] || [ -h ~/.zshrc ]; then if [ $KEEP_ZSHRC = yes ]; then echo "${YELLOW}Found ~/.zshrc.${RESET} ${GREEN}Keeping...${RESET}" return fi if [ -e "$OLD_ZSHRC" ]; then OLD_OLD_ZSHRC="${OLD_ZSHRC}-$(date +%Y-%m-%d_%H-%M-%S)" if [ -e "$OLD_OLD_ZSHRC" ]; then error "$OLD_OLD_ZSHRC exists.
