ubuntu使用oh my zsh美化终端

1. 安装zsh和oh my zsh

首先安装zsh

sudo apt install zsh

然后查看本地有哪些shell可以使用

cat /etc/shells 

将默认的shell切换为zsh

chsh -s /bin/zsh

然后安装oh-my-zsh，参考官网提供的两种安装方式

sh -c "$(wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh -O -)"

或者

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

2. 修改zsh主题

oh-my-zsh内置了很多主题，可以进入路径~/.oh-my-zsh/themes下进行查看，如图所示

如果想要修改成自己喜欢的主题，可以

sudo gedit ~/.zshrc

然后找到ZSH_THEME="xxxx"，将其修改为已经安装的主题就行，保存然后退出，打开终端

source ~/.zshrc

这里推荐一个主题powerlevel10k，只需要将其git到～/.oh-my-zsh/custom/themes/powerlevel10k目录下即可，

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

然后再配置~/.zshrc文件

sudo gedit ~/.zshrc

修改为ZSH_THEME="powerlevel10k/powerlevel10k"，然后source

source ~/.zshrc

效果如下

3. 安装zsh插件

zsh的内置插件可以在路径～/.oh-my-zsh/plugins中进行查看，如下图所示

别的插件可以在：awesome-zsh-plugins进行查找

这里推荐两个插件，第一个是支持自动补全的zsh-autosuggestions

zsh-autosuggestions

我们只需要将其git到路径~/.oh-my-zsh/custom/plugins中，然后配置~/.zshrc文件即可

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

然后在~/.zshrc中把插件添加到插件列表中

plugins=(# other plugins...zsh-autosuggestions  # 插件之间使用空格隔开
)

然后source一下

source ~/.zshrc

zsh-syntax-highlighting 是一个命令语法校验插件，在输入命令的过程中，若指令不合法，则指令显示为红色，若指令合法就会显示为绿色。

按照相同的流程，我们即可配置这个插件，将其git到~/.oh-my-zsh/custom/plugins中

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-syntax-highlighting

然后在~/.zshrc中将zsh-syntax-highlighting插入插件列表

plugins=(# other plugins...zsh-autosuggestionszsh-syntax-highlighting
)

然后source一下

source ~/.zshrc

4. 将.bashrc移植到.zshrc

笔者之前一直在使用bash然后配置了一些资源路径，比如ros、anaconda还有一些别的环境变量比如cuda、cudnn等，要进行移植其实很简单，大部分的时候我们只需要将xxx.bash替换为xxx.zsh即可，然后别的一些环境变量的设置可以直接复制过去。举个例子

这是我的.bashrc自己添加的部分

# >>> clash <<<
export PATH=$PATH:/opt/clash# >>> cuda <<<
export PATH=$PATH:/usr/local/cuda/bin  
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64  
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda/lib64
# export CUDA_HOME=/usr/local/cuda-11.1# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/your_usr_name/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; theneval "$__conda_setup"
elseif [ -f "/home/your_usr_name/miniconda3/etc/profile.d/conda.sh" ]; then. "/home/your_usr_name/miniconda3/etc/profile.d/conda.sh"elseexport PATH="/home/your_usr_name/miniconda3/bin:$PATH"fi
fi
unset __conda_setup
# <<< conda initialize <<<# >>> ros noetic <<< 
source /opt/ros/noetic/setup.bash
# >>> ros2 foxy <<<
# source /opt/ros/foxy/setup.bash# >>> ur5 workspace <<<
source /home/your_usr_name/Documents/catkin_ur5/devel/setup.bash
# >>> frcobot workspace <<<
source /home/your_usr_name/Documents/catkin_frco/devel/setup.bash# >>> pyorbbecsdk <<<
export PYTHONPATH=$PYTHONPATH:/home/your_usr_name/Documents/pyorbbecsdk/install/lib/

我将其放在.zshrc中就修改如下

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/your_usr_name/miniconda3/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; theneval "$__conda_setup"
elseif [ -f "/home/your_usr_name/miniconda3/etc/profile.d/conda.sh" ]; then. "/home/sjhyour_usr_nameminiconda3/etc/profile.d/conda.sh"elseexport PATH="/home/your_usr_name/miniconda3/bin:$PATH"fi
fi
unset __conda_setup
# <<< conda initialize <<<# >>> clash <<<
export PATH=$PATH:/opt/clash# >>> cuda <<<
export PATH=$PATH:/usr/local/cuda/bin  
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64  
export LIBRARY_PATH=$LIBRARY_PATH:/usr/local/cuda/lib64
# export CUDA_HOME=/usr/local/cuda-11.1# >>> ros noetic <<< 
source /opt/ros/noetic/setup.zsh
# >>> ros2 foxy <<<
# source /opt/ros/foxy/setup.zsh# >>> ur5 workspace <<<
source /home/your_usr_name/Documents/catkin_ur5/devel/setup.zsh
# >>> frcobot workspace <<<
source /home/your_usr_name/Documents/catkin_frco/devel/setup.zsh# >>> pyorbbecsdk <<<
export PYTHONPATH=$PYTHONPATH:/home/your_usr_name/Documents/pyorbbecsdk/install/lib/
