zsh is a powerful terminal under linux, but the default terminal of ubuntu is bash. ohmyzsh is an extension tool set based on zsh, which provides rich extension functions.
Install Zsh
sudo apt-get install zsh
Check which terminals have been installed in the current system, if there is /bin/zshthis default terminal, we will go to the next step
cat /etc/shells
Here we installed zsh, but also need to set him as the default terminal
chsh -s /bin/zsh
But although we have successfully set up, our terminal is still bash, and we can use the command to view the current terminal
echo $SHELL
Here, my system needs to be restarted to modify the default terminal.
Install Oh-My-Zsh
Oh-My-Zsh is installed by running one of the following commands in Terminal. You can install it via command line using curl, wget or other similar tools.
| method | Order |
|---|---|
| wget | sh -c “$(wget -O- https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)” |
| curl | sh -c “$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)” |
| fetch | sh -c “$(fetch -o - https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)” |
Here we use some download tools, whichever one is used, all three are fine. After the installation is complete, you can reopen a terminal. That is ZSH with Oh-My-Zsh installed.
Using Oh-My-Zsh
plug-in
Once you find a plugin (or a few) that you want to use with Oh My Zsh, you need to .zshrcenable them in the file. You will $HOMEfind the zshrc file in the directory. Open it with your favorite text editor and you'll see a place listing all the plugins you want to load.
vim ~/.zshrc
The plugin settings are as follows
# 默认初始安装只会启用一个git插件，插件由空格、制表符、新行分隔。不要在它们之间使用逗号，否则会中断。
plugins=(git)
Oh-My-Zsh comes with many plugins, we can find the default plugins at this address (https://github.com/ohmyzsh/ohmyzsh/wiki/Plugins).
Here are two more useful plug-in recommendations
zsh-autosuggestions
This is an autocomplete plugin
git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
zsh-syntax-highlighting
This is a display highlighting plugin
git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting
configuration file
This is how the above two plug-ins are written into the configuration file. We can add what we want later by ourselves.
plugins=(git zsh-autosuggestions zsh-syntax-highlighting)
theme
The built-in theme can be viewed at this URL (https://github.com/ohmyzsh/ohmyzsh/wiki/Themes)
The configuration of the theme is also in .zshrcthe file
ZSH_THEME="robbyrussell"
I prefer this default theme, but you can look at the theme in the wiki, there are screenshots, just replace it with whichever you like.
to refresh
After installation, you need to refresh the configuration file to take effect
source ~/.zshrc
But restarting a terminal directly can also
Uninstall Oh-My-Zsh
uninstall_oh_my_zsh
Running this command will not only remove Oh-My-Zsh, but will also return your shell to the default and previous configuration of zsh or bash.
But it is said that this thing can not be deleted. . . .
