一键安装ohmyzsh常用插件的脚本

功能

脚本实现了下载安装ohmyzsh的常用插件功能，并替换~/.zshrc文件的plugins字段配置；
安装的plugins分别为：

zsh-autosuggestions：zsh-autosuggestions 此插件实现了自动补全语法功能，会自动缓存敲过一次的终端命令，并且在下次输入同样命令的前几个字符时，联想出命令；

zsh-syntax-highlighting：zsh-syntax-highlighting 此插件可以自动分析输入的Linux 及常用命令是否正确；

z：z 此插件实现了自动跳转目录功能，插件会以哈希表的形式自动记录你访问过的路径，在下次访问时，直接输入文件目录的最后一级，按tab即可联想出；

使用

使用前本地需安装 ohmyzsh ，因GitHub国内访问环境不稳定，因此通过gitee 镜像安装；

sh -c "$(curl -fsSL https://gitee.com/xrxiao/ohmyzsh/raw/master/tools/install.sh)"

使用upgrade_oh_my_zsh命令可以手动更新升级ohmyzsh。

使用以下脚本自动安装ohmyzsh的常用plugins。脚本自动检测本地是否安装ohmyzsh，如果没安装过，会直接退出；

# 将某个文件中的字符串替换为新字符串 mac环境和linux环境 sed -i 使用不同

# Linux使用：https://www.cnblogs.com/A121/p/10621152.html

# eg:把文件中的jack替换成tom，并给源文件添加.backup后缀并备份；添加/g是全部替换，默认每行只替换一次。
# sed -i ".backup" 's/jack/tom/g' $file_zshrc

sed -i ".backup" "s/$plugins/$replacePlugins/" $file_zshrc
