There are three basic tools for using terminals ：zsh,vim,tmux. Then I will introduce the three tools one by one .

be familiar with Linux System or Mac Systematic , about 「bash」 No strangers .bash It is the most basic script environment for user and system interaction . and zsh（Z shell） yes bash An alternative to , He is bash There are a lot of optimizations , Whether using commands , appearance , Experience , It can make users more convenient and smooth to use Terminal.

This article mainly introduces zsh,oh-my-zsh Installation , Basic environment configuration , And some practical plug-ins . The configuration of theme style will be introduced separately .

zsh Mainly through oh-my-zsh Development of , It has realized many easy-to-use functions .

github website ：ohmyzsh/ohmyzsh​github.com/ohmyzsh/ohmyzsh

install zsh,oh-my-zsh

• Mac System installation zsh Very simple ：

$ brew install zsh

zsh It's installed in /bin/zsh In the path

The system default environment is bash, from bash Get into zsh Just input ：zsh that will do , The opposite is true .

• install oh-my-zsh

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

• After installation, you need to configure each time you open terminal The default is zsh.

$ chsh -s /bin/zsh

• zsh Will be generated under the user path .zshrc file , And bashrc similar , Add the default environment variables .

Common plug-in configurations

• Path case ignored

zsh By default, the path on is case insensitive , The advantage is that you often forget that a folder is capitalized when entering a path ,zsh Will automatically change your lower case input to upper case ,「tab」 The prompt function of is the same , Will prompt whether upper or lower case , This greatly reduces the probability of the wrong path .

• Change the theme

zsh The official has brought many different styles of themes , You can customize the settings , stay ~/.zshrc Just change one line inside .

Random themes can be opened every time zsh Use different themes ：

ZSH_THEME="random"

Change to another topic 、github The theme of needs to be configured separately , I will not introduce .

• autojump

God level plug in ！！ When there are many nested path levels , We use 「cd」 Level by level input +Tab Efficiency is very low ,「autojump」 It can be used according to the frequency of the path used by the user , According to the key words entered , Jump directly to the path , The keyword is one section of the path .

https://github.com/wting/autojump​github.com/wting/autojump

install autojump

$ brew install autojump

for example , We want to access a folder , If you use the normal command to input

$ cd  Absolute path 

But if 「autojump」, Just input

$ j  Path keywords 

You can see that you directly jump into the path .

「autojump」 Will make a sort according to the frequency of keyword use , Sometimes some paths have similar keywords , Use 「tab」 You can view the sorting , for example ：

Which one do you want to visit , Enter the corresponding number .

• zsh-autosuggestion

Generally, enter the path , To command, you need to click 「tab」 Will prompt you some complete information ,「zsh-autosuggestion」 It will automatically fill in the most likely instruction when entering , And it will be updated with the content entered later , And all possible options will be displayed below , Press... When it meets your needs 「tab」 that will do .

• zsh stay Linux The system is also fully supported ,Linux The installation of plug-ins under the system can be viewed GitHub In the project readme, There is no talk here ;
• bash and zsh basic 99% It's universal , But sometimes there are problems , I have only two problems here ： install anaconda When oh-my-zsh Need configuration ,snpe Our environment only supports bash Environmental Science .
• The plug-ins and themes are placed in ~/.oh-my-zsh/plugins and ~/.oh-my-zsh/themes In two folders , Easy to manage and use .
