安装iterm
官网https://www.iterm2.com/,下载压缩包，解压就行。
安装 oh my zsh
$ sh -c "$(curl -fsSL https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh)" or
$ sh -c "$(wget https://raw.githubusercontent.com/robbyrussell/oh-my-zsh/master/tools/install.sh -O -)"
$ cp ~/.oh-my-zsh/templates/zshrc.zsh-template ~/.zshrc
切换bash环境到zsh
$ chsh -s /bin/zsh
# 切换回来
$ chsh -s /bin/bash
控制台输入汉字显示乱码
vim ~/.zshrc 添加：
export LC_ALL=zh_CN.UTF-8
export LANG=zh_CN.UTF-8bb
securecrf中vim选中不能复制却变成visual模式
与securecrt没关系，和vim的配置有关系
rm -rf ~/.vimrcbrew uninstall vimbrew install vim
