iTerm2 是一款功能强大的终端工具,也可以说是 Terminal 的替代品,也可以说是 iTerm 的后继产品。它适用于 macOS 10.12 或更高版本的 macOS。
它支持分窗口操作、自动补齐、粘贴历史、回放功能、全屏等功能,是一款非常强大、非常值得推荐的终端工具。
注意:
如果你的 Mac 上没有安装 brew 命令,请先执行如下命令进行安装:
$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
iTerm2 最常用的主题是 Solarized Dark theme,下载地址:https://ethanschoonover.com/solarized
下载的是压缩文件,你先解压一下,然后打开 iTerm2,按 【Command + , 】键,打开 Preferences 配置界面,然后 Profiles -> Colors -> Color Presets -> Import,选择刚才解压的 solarized -> iterm2-colors-solarized -> Solarized Dark.itermcolors 文件,导入成功,最后选择 Solarized Dark 主题,就可以了,如下所示:
该工具主题有很多,可以根据自己的爱好进行选择。
oh-my-zsh 是对主题的进一步扩展,Github 地址:https://github.com/ohmyzsh/ohmyzsh
你可以通过 curl 或 wget 命令进行安装:
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
sh -c "$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
例如,我这里通过 curl 命令进行安装:
$ sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"

安装好之后,需要把 zsh 设置为当前用户的默认 shell(这样新建命令的时候才会使用 zsh):
$ chsh -s /bin/zsh
```
然后,我们用 vim 命令编辑 ~/.zshrc 文件,将主题配置修改为 ZSH_THEME="agnoster"。
```javascript
$ vim ~/.zshrc
# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH
# Path to your oh-my-zsh installation.
export ZSH="/Users/linan/.oh-my-zsh"
# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/robbyrussell/oh-my-zsh/wiki/Themes
ZSH_THEME="agnoster" // 修改主题
agnoster 是比较常用的 zsh 主题之一,你可以挑选你喜欢的主题,zsh 主题列表:https://github.com/ohmyzsh/ohmyzsh/wiki/themes
使用上面的主题,需要 Meslo 字体支持,要不然会出现乱码的情况,字体下载地址:Meslo LG M Regular for Powerline.ttf
下载好之后,直接在 macOS 中双击安装即可。
然后打开 iTerm2,按【Command + , 】键,打开 Preferences 配置界面,然后 Profiles -> Text -> Font -> Chanage Font,选择 Meslo LG M Regular for Powerline 字体。
当然,如果你觉得默认的12px字体大小不合适,可以自己进行修改。
另外,VS Code 的终端字体,也需要进行配置,打开 VS Code,按 Command + ,键,打开用户配置,搜索 fontFamily,然后将右边的配置增加"terminal.integrated.fontFamily": "Meslo LG M for Powerline",示例:
效果就是上面截图的那样,特殊命令和错误命令,会有高亮显示。
使用 Homebrew 安装:
$ brew install zsh-syntax-highlighting
安装成功之后,用 vim 命令编辑 ~/.zshrc 文件,在最后一行增加下面配置:
...................
# Compilation flags
# export ARCHFLAGS="-arch x86_64"
# Set personal aliases, overriding those provided by oh-my-zsh libs,
# plugins, and themes. Aliases can be placed here, though oh-my-zsh
# users are encouraged to define aliases within the ZSH_CUSTOM folder.
# For a full list of active aliases, run `alias`.
#
# Example aliases
# alias zshconfig="mate ~/.zshrc"
# alias ohmyzsh="mate ~/.oh-my-zsh"
source /usr/local/share/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh
保存后,执行变量生效命令:
source /etc/profile
这个功能是非常实用的,可以方便我们快速的敲命令。
配置步骤,先克隆 zsh-autosuggestions 项目,到指定目录:
$ git clone https://github.com/zsh-users/zsh-autosuggestions ~/.oh-my-zsh/custom/plugins/zsh-autosuggestions
然后,用 vim 命令编辑 ~/.zshrc 文件,找到 plugins 配置,增加 zsh-autosuggestions 插件:
# Would you like to use another custom folder than $ZSH/custom?
# ZSH_CUSTOM=/path/to/new-custom-folder
# Which plugins would you like to load?
# Standard plugins can be found in $ZSH/plugins/
# Custom plugins may be added to $ZSH_CUSTOM/plugins/
# Example format: plugins=(rails git textmate ruby lighthouse)
# Add wisely, as too many plugins slow down shell startup.
plugins=(git zsh-autosuggestions)
> 注意:
上面声明高亮,如果配置不生效的话,可以在 plugins 配置,再增加 zsh-syntax-highlighting 插件试试。
有时候因为自动填充的颜色和背景颜色很相似,以至于自动填充没有效果,我们可以手动更改下自动填充的颜色配置,我修改的颜色值为:3a717f,示例:
主要是按住 option + → or ← 键,在命令的开始和结尾跳转切换,原本是不生效的,需要手动开启下。
打开 iTerm2,按 Command + , 键,打开 Preferences 配置界面,然后 Profiles → Keys → Load Preset... → Natural Text Editing,就可以了。
这个功能也非常使用,就是通过快捷键,可以快速的隐藏和打开 iTerm2,示例配置快捷键:( Commond + . ):
有时候我们的用户名和主机名太长,比如我的 pengzhenjin@MacBook-Pro,终端显示的时候会很不好看,我们可以手动去除。用 vim 命令编辑 ~/.zshrc 文件,增加 DEFAULT_USER="pengzhenjin" 配置,如:
# If you come from bash you might have to change your $PATH.
# export PATH=$HOME/bin:/usr/local/bin:$PATH
# Path to your oh-my-zsh installation.
export ZSH="/Users/user/.oh-my-zsh"
# Set name of the theme to load --- if set to "random", it will
# load a random theme each time oh-my-zsh is loaded, in which case,
# to know which specific one was loaded, run: echo $RANDOM_THEME
# See https://github.com/ohmyzsh/ohmyzsh/wiki/Themes
ZSH_THEME="agnoster"
DEFAULT_USER="pengzhenjin"
用 vim 命令编辑 ~/.zshrc 文件,增加下面配置:
# proxy list
alias proxy='export all_proxy=socks5://127.0.0.1:1086'
alias unproxy='unset all_proxy'
iTerm2 需要新建标签页,才有效果:
$ proxy
$ curl ip.cn
当前 IP:185.225.14.5 来自:美国
$ unproxy
$ curl ip.cn
当前 IP:115.236.186.130 来自:浙江省杭州市 电信
我们可以测试下:
$ curl https://packages.cloud.google.com/yum/repos/kubernetes-el7-x86_64
