Oh My ZSH让你的终端美如画

前言

无意中发现这个插件Oh My ZSH，之前也有在一些视频中看到过，一直好奇是什么插件。怎么早没发现这么好用的插件啊。

安装方法

官网： https://ohmyz.sh/

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

国内源加速：

sh -c "$(curl -fsSL https://gitee.com/lxyoucan/tools/raw/master/common/ohmyzshinstall.sh)"

安装完成后，打开终端会出现：

[oh-my-zsh] Insecure completion-dependent directories detected:
drwxrwxrwx  3 itkey  admin   96 12 17 10:26 /usr/local/share/zsh
drwxrwxrwx  4 itkey  admin  128 12 17 10:29 /usr/local/share/zsh/site-functions

[oh-my-zsh] For safety, we will not load completions from these directories until
[oh-my-zsh] you fix their permissions and ownership and restart zsh.
[oh-my-zsh] See the above list for directories with group or other writability.

[oh-my-zsh] To fix your permissions you can do so by disabling
[oh-my-zsh] the write permission of "group" and "others" and making sure that the
[oh-my-zsh] owner of these directories is either root or your current user.
[oh-my-zsh] The following command may help:
[oh-my-zsh]     compaudit | xargs chmod g-w,o-w

[oh-my-zsh] If the above didn't help or you want to skip the verification of
[oh-my-zsh] insecure directories you can set the variable ZSH_DISABLE_COMPFIX to
[oh-my-zsh] "true" before oh-my-zsh is sourced in your zshrc file.

根据提示，执行以下语句：

compaudit | xargs chmod gw，ow

下次打开终端就没有这个提示了。

安装高亮显示插件

我首先要做的是安装一个名为 zsh-syntax-highlighting的插件。它为ZSH Shell提供语法高亮显示。

cd $HOME/.oh-my-zsh/plugins
#下载代码
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git
#自动配置
echo "source ${(q-)PWD}/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh" >> ${ZDOTDIR:-$HOME}/.zshrc

最后一行，就是自动修改 ~/.zshrc,在最后一行加入

source /Users/itkey/.oh-my-zsh/plugins/zsh-syntax-highlighting/zsh-syntax-highlighting.zsh

智能提示 zsh-autosuggestions

cd $HOME/.oh-my-zsh/plugins
#下载代码
git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

修改~/.zshrc增加插件引用 plugins=(zsh-autosuggestions)

主题设置

如多主题到这里看吧： https://github.com/ohmyzsh/ohmyzsh/wiki/Themes

我挑一个自己喜欢的主题。 这主题要先安装字体：

1. 安装 powerline 字体

# clone
git clone https://github.com/powerline/fonts.git --depth=1
# install
cd fonts
./install.sh
# clean-up a bit
cd ..
rm -rf fonts

2. iTerm中设置字体
3. 修改~/.zshrc ZSH_THEME=“agnoster”

VSCODE中设置 在你的设置文件中 (Code | Preferences | Settings)

增加如下这行：

"terminal.integrated.fontFamily": "Meslo LG S DZ for Powerline"

设置 vim 可配色

终端输入vim .vimrc，设置内容如下，

syntax on
set number
set ruler

临时不想用Oh My ZSH

如果体验以后，发现可能不适合你。或者都临时换成以前的zsh怎么办呢？ 肉吃多了想吃点素的。

方法一：

zsh -f

这只是临时的，下次打开终端还是会以 Oh My ZSH打开。

方法二：

安装Oh My ZSH以前会自动把我们之前的~/.zshrc ，重命名为~/.zshrc.pre-oh-my-zsh。 修改~/.zshrc为安装Oh My ZSH这前的配置即可。

1. 从Oh My ZSH切换到ZSH

#备份Oh My ZSH的配置，方便后面还原
cp ~/.zshrc ~/.zshrc.bak-oh-my-zsh
#切换为原配置
cp ~/.zshrc.pre-oh-my-zsh ~/.zshrc

2. 从ZSH切换到Oh My ZSH

#前提是之前执行过从Oh My ZSH切换到ZSH
cp ~/.zshrc.bak-oh-my-zsh ~/.zshrc

重新开启终端生效。反正就捣鼓这两个文件~/.zshrc 和 ~/.zshrc.pre-oh-my-zsh，如果你喜欢可以把这个操作做成快捷指令方便来回切换。

卸载

这么好的东西你要卸载了？心不会痛吗？好吧，那么它来了。

uninstall_oh_my_zsh

重启以后它就没有了。变回它原来的样子了。 友情提醒：卸载会把你安装的插件一起卸载了，如果觉得有需要就备份一下吧。
