[Ubuntu20]安装zsh，ohmyzsh并配置

安装zsh

sudo apt-get install zsh


安装git

sudo apt-get install git


安装oh-my-zsh&＃xff08;轻量级配置zsh的开源软件&＃xff09;

以下三种方式任选其一

1. 通过在github上的脚本安装

   sh -c "$(curl -fsSL https://raw.github.com/robbyrussell/oh-my-zsh/master/tools/install.sh)"


2. 访问github如果有困难可以访问gitee的镜像

   sh -c "$(curl -fsSL https://gitee.com/mirrors/oh-my-zsh/raw/master/tools/install.sh)"


3. 服务器实在不行可以先想办法下载下来install.sh&＃xff0c;上传到服务器中&＃xff0c;可以通过ftp或者其他方法。这里我推荐lrzsz&＃xff0c;使用xshell直接拖入就可以
   安装lrzsz

   sudo apt-get install lrzsz


   chmod 775 install.sh
./install.sh


至此oh-my-zsh就安装完了

下载 zsh-syntax-highlighting 语法高亮插件

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


下载 zsh-autosuggestions 自动提示插件

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


修改用户默认shell

vim /etc/passwd


找到用户那一行

user:x:1000:1000:user:/home/user:/bin/bash


/bin/bash 是用户默认shell
修改为/usr/bin/zsh

oh-my-zsh更换位置

oh-my-zsh默认会安装到

~/.oh-my-zsh


如果想其他用户一起使用&＃xff0c;可以放到一个公共的位置&＃xff0c;比如

/usr/local/


可以用以下命令更换位置

mv ~/.oh-my-zsh /usr/local/.oh-my-zsh


修改zsh配置文件

vim ~/.zshrc
修改.oh-my-zsh位置

export ZSH&＃61;"/usr/local/.oh-my-zsh"


修改主题

ZSH_THEME&＃61;"ys"


设置别名或环境变量

之前在bash中的别名或环境变量可以加在~/.zshrc底部
在这里记录/分享我常用的环境变量

alias tailf&＃61;&＃39;tail -f&＃39;
alias dc&＃61;&＃39;docker-compose&＃39;
alias ll&＃61;&＃39;ls -alh&＃39;#Rebind HOME and END to do the decent thing:
bindkey &＃39;\e[1~&＃39; beginning-of-line
bindkey &＃39;\e[4~&＃39; end-of-line
case $TERM in (xterm*)
bindkey &＃39;\eOH&＃39; beginning-of-line
bindkey &＃39;\eOF&＃39; end-of-line
esac#To discover what keycode is being sent, hit ^v
#and then the key you want to test.#And DEL too, as well as PGDN and insert:
bindkey &＃39;\e[3~&＃39; delete-char
bindkey &＃39;\e[6~&＃39; end-of-history
bindkey &＃39;\e[2~&＃39; redisplay#Now bind pgup to paste the last word of the last command,
bindkey &＃39;\e[5~&＃39; insert-last-word
