# 02 powershell alias

## 1.使用 powershell 的 function 来实现

```bash
PS> function get-gitstatus { git status }

PS> get-gitstatus
# On branch master
nothing to commit (working directory clean)

PS> Set-Alias -Name gs -Value get-gitstatus

PS> gs
# On branch master
nothing to commit (working directory clean)
```

技术点：\
PS > function \[name] { \[command] }\
PS > Set-Alias -Name \[name] -Value \[command]

## 2.持久化保存

> 使用 profile 来保存一些初始化工作\
> 四种不同的 profile 脚本\
> $pshome 为 C:\Windows\System32\WindowsPowerShell\v1.0 可以将 example 文件夹中的 profile.ps1 复制出来

| Profile  | 描述                               | 位置                                               |
| -------- | -------------------------------- | ------------------------------------------------ |
| 所有用户     | 所有用户共有的profile                   | $pshome\profile.ps1                              |
| 所有用户（私有） | powershell.exe 中验证。              | $pshome\Microsoft.PowerShell\_profile.ps1        |
| 当前用户     | 当前用户的profile                     | $((Split-Path $profile -Parent)+ “\profile.ps1”) |
| 当前用户（私有） | 当前用户的profile；只在Powershell.exe中验证 | $profile                                         |
