.zshenv
.zshenv中存放的环境变量配置项在任何场景下都能被读取，这里通常把$PATH等变量写在这里，这样无论是在交互shell，或者运行程序都会读取此文件

.zshrc
.zshrc主要用在交互shell

zlogin
.zlogin则在login shell的时候读取，比如系统启动的时候会读取此文件

zprofile
.zprofile是.zlogin的替代品，如果使用了.zlogin就不必再关心此文件

.zshenv → [.zprofile if login] → [.zshrc if interactive] → [.zlogin if login] → [.zlogout sometimes].

git config --global user.name ""
git config --global user.email ""

1.open/vim /etc/profile (建议不修改这个文件)
全局（公有）配置，不管是哪个用户，登录时都会读取该文件。

2./etc/bashrc (一般在这个文件中添加系统环境变量)
全局（共有）配置，bash shell 执行时，不管是何种方式，都会读取此文件。

3.～/.bash_profile（一般在这个文件中添加用户级环境变化）
（注：Linux里面是 .bashrc而Mac是.bash_profile）
若bash shell是以login方式执行时，才会读取此文件。该文件仅仅执行一次！默认情况下，他设置一些环境变量。

vim ~/.bash_profile
i键编辑模式

手动生效

brew list 软件名 来显示路径
1、通过brew install安装应用最先是放在/usr/local/Cellar/目录下。
2、有些应用会自动创建链接放在/usr/bin或者/usr/sbin，同时也会将整个文件夹放在/usr/local
3、可以使用 brew list 软件名 (比如 brew list oclint)确定安装位置。

路径查询
brew --prefix nvm
/opt/homebrew/opt/nvm

brew list nvm
/opt/homebrew/Cellar/nvm/0.39.1/etc/bash_completion.d/nvm
/opt/homebrew/Cellar/nvm/0.39.1/nvm-exec
/opt/homebrew/Cellar/nvm/0.39.1/nvm.sh

官方说明中建议将英特尔版本安装在/usr/local路径，arm版本安装在/opt/homebrew路径。

which brew
/opt/homebrew/bin/brew

当执行brew install xxxx应用时，会将在目录/usr/local/Cellar下，创建名为xxxx的目录，然后把所有下载的资源文件存放在这个目录下。

当执行brew uninstall xxxx应用时，会删除/usr/local/Cellar/xxxx目录。

当执行brew cleanup时，会将存放在/usr/local/Cellar目录下的同一个应用的所有低版本的程序包全部删除，只保留最新安装的程序包。

brew cleanup
Removing: /Users/jeskson/Library/Logs/Homebrew/macos-term-size... (64B)
Removing: /Users/jeskson/Library/Logs/Homebrew/n... (64B)
Removing: /Users/jeskson/Library/Logs/Homebrew/node@14... (64B)
Removing: /Users/jeskson/Library/Logs/Homebrew/node@12... (64B)

brew 还会创建自己的缓存目录/Users/<用户名>/Library/Caches/Homebrew，brew会将其作为资源下载的缓存目录。

其他应用也与Homebrew应用类似，都会在/Users/<用户名>/Library/Caches目录下，建立自己的缓存目录，并在自己的缓存目录下存放自己的缓存文件。

/Users/jeskson/Library

可以通过删除/Users/<用户名>/Libray/Caches这个目录下的全部缓存文件，以此释放一些被占用的存储空间，增加可用存储空间。可以在访达工具窗口下进行删除操作，也可在系统终端下输入sudo rm -rf Users/<用户名>/Library/Caches指令进行删除，但删除前要确认删除这些文件所带来的影响，如果不合适，就尽量不要删除。

.bash_profile
.zshrc
