# PowerShell 7 提示符美化
|
||
|
||
> PowerShell 有两个主流的提示符美化工具：[Oh My Posh](https://ohmyposh.dev/) 和 [Starship](https://starship.dev/)，二者选其一即可。
|
||
|
||
## 安装 PowerShell 7
|
||
|
||
`PowerShell 7` 指的不是系统自带的 `powershell` ，而是新下载的(微软官方出品)，当然这个教程也适用于系统自带的 `powershell`
|
||
|
||
微软官方文档地址：https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows?view=powershell-7.2
|
||
下载地址：https://github.com/PowerShell/PowerShell/releases
|
||
或者可通过 Winget 方式下载安装
|
||
|
||
```powershell
|
||
winget search --id Microsoft.PowerShell
|
||
```
|
||
|
||
Output
|
||
|
||
```powershell
|
||
Name Id Version Source
|
||
---------------------------------------------------------------
|
||
PowerShell Microsoft.PowerShell 7.5.4.0 winget
|
||
PowerShell Preview Microsoft.PowerShell.Preview 7.6.0.5 winget
|
||
```
|
||
|
||
使用 `--id` 参数安装 PowerShell 或 PowerShell 预览版
|
||
|
||
```powershell
|
||
winget install --id Microsoft.PowerShell --source winget
|
||
```
|
||
|
||
```powershell
|
||
winget install --id Microsoft.PowerShell.Preview --source winget
|
||
```
|
||
|
||
## Oh My Posh
|
||
|
||
官方文档地址：https://ohmyposh.dev/
|
||
|
||
### 安装
|
||
|
||
最好在管理员模式下运行 `powershell`
|
||
|
||
下载安装，在 `powershell` 命令行中输入
|
||
|
||
```powershell
|
||
winget install oh-my-posh
|
||
```
|
||
|
||
在 `powershell` 命令行中输入下面命令，打开 `$Profile` 进行设置，如果系统提示不存文件，是否创建，请点击创建
|
||
|
||
```powershell
|
||
notepad $Profile
|
||
```
|
||
|
||
将以下命令添加到 `$Profile` 文件中
|
||
|
||
```powershell
|
||
oh-my-posh init pwsh | Invoke-Expression
|
||
```
|
||
|
||
应用修改，则直接在命令行中执行 `. $Profile` ，如果出现错误等问题，请尝试关闭所有 `powershell` 命令窗口，重新打开，一般都会正常显示
|
||
|
||
### 配置环境变量
|
||
|
||
配置 `POSH_THEMES_PATH` 环境变量，最好配置成系统级别的，路径在 `C:\Users\<当前登录用户>\AppData\Local\Programs\oh-my-posh\themes` 下面。
|
||
|
||
### 更改主题
|
||
|
||
在 `powerShell` 命令行中输入 `Get-ChildItem $env:POSH_THEMES_PATH` 来获取所有的已安装主题
|
||
|
||
**预览主题（官方推荐方式）：** 由于在终端里一次性渲染所有主题会很卡，官方建议直接去网页上看截图，然后记住名字即可。
|
||
|
||
- **[Oh My Posh 官方主题预览页 (Themes)](https://ohmyposh.dev/docs/themes)**
|
||
|
||
编辑 `$Profile` 文件
|
||
|
||
```powershell
|
||
notepad $Profile
|
||
```
|
||
|
||
把 `oh-my-posh init pwsh ...` 的部分後面加上 `--config "$env:POSH_THEMES_PATH/{主題名稱}.omp.json"`。
|
||
将其内部文字改为：
|
||
|
||
```powershell
|
||
oh-my-posh init pwsh --config "$env:POSH_THEMES_PATH/montys.omp.json" | Invoke-Expression
|
||
```
|
||
|
||
## Starship
|
||
|
||
[Starship](https://starship.dev/) 是跨平台的提示符工具，支持 Windows、Linux、macOS。与 Oh My Posh 功能类似，二者选其一即可。
|
||
|
||
### 安装
|
||
|
||
```powershell
|
||
winget install --id Starship.Starship
|
||
```
|
||
|
||
### 配置文件位置
|
||
|
||
Windows 下配置文件路径：`~/.config/starship.toml`
|
||
|
||
```powershell
|
||
# 创建配置目录和文件
|
||
mkdir -p ~/.config
|
||
New-Item -Path ~/.config/starship.toml -ItemType File -Force
|
||
|
||
# 用 VSCode 打开编辑
|
||
code ~/.config/starship.toml
|
||
```
|
||
|
||
### 初始化
|
||
|
||
在 `$PROFILE` 文件中添加：
|
||
|
||
```powershell
|
||
# Starship 初始化（必须放最后）
|
||
Invoke-Expression (&starship init powershell)
|
||
```
|
||
|
||
### 完整配置（Catppuccin Mocha 主题）
|
||
|
||
将以下内容粘贴到 `starship.toml` 文件中：
|
||
|
||
```toml
|
||
"$schema" = 'https://starship.rs/config-schema.json'
|
||

|
||
|
||
> 参考：[PowerShell 终端增强配置指南](https://mp.weixin.qq.com/s/DV-T4Tr4KaonFdgutuzhQQ)
|
||
|
||
### 前置准备
|
||
|
||
#### 确认 PowerShell 版本
|
||
|
||
```powershell
|
||
$PSVersionTable.PSVersion
|
||
```
|
||
|
||
- 主版本号为 `5` → 使用 **PS5.1 方案**
|
||
- 主版本号为 `7` → 使用 **PS7+ 方案**
|
||
|
||
#### 确认 Profile 文件路径
|
||
|
||
```powershell
|
||
# 查看路径
|
||
echo $PROFILE
|
||
|
||
# 若文件不存在则创建
|
||
if (!(Test-Path $PROFILE)) {
|
||
New-Item -ItemType File -Path $PROFILE -Force
|
||
}
|
||
|
||
# 用 VSCode 打开编辑
|
||
code $PROFILE
|
||
```
|
||
|
||
> PS5.1 的 Profile 路径通常为：`C:\Users\<用户名>\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1`
|
||
>
|
||
> PS7+ 的 Profile 路径通常为：`C:\Users\<用户名>\Documents\PowerShell\Microsoft.PowerShell_profile.ps1`
|
||
>
|
||
> 两个版本的 Profile **互相独立**，需分别配置。
|
||
|
||
#### 设置执行策略（如遇权限报错）
|
||
|
||
```powershell
|
||
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
|
||
```
|
||
|
||

|
||
|
||
### 功能说明
|
||
|
||
#### 动态窗口标题
|
||
|
||
标题由以下三部分拼接而成：
|
||
|
||
```
|
||
PS · <当前目录名> [<Git分支>] <管理员标识>
|
||
```
|
||
|
||
**示例效果：**
|
||
|
||
| 场景 | 窗口标题 |
|
||
|------|----------|
|
||
| 普通目录 | `PS · Downloads` |
|
||
| Git 仓库 | `PS · my-project [main]` |
|
||
| 管理员身份 | `PS · System32 ⚡ADMIN` |
|
||
| 管理员 + Git | `PS · infra [feat/deploy] ⚡ADMIN` |
|
||
|
||
**实现原理：** 利用 Starship 预留的 `Invoke-Starship-PreCommand` 钩子函数，在每次渲染 Prompt 之前执行，与 Starship 完全兼容，无冲突。
|
||
|
||
#### 自动补全配置
|
||
|
||
配置分为四个层次，可按需选择叠加：
|
||
|
||
| 层次 | 功能 | 说明 |
|
||
|------|------|------|
|
||
| Layer 1 | PSReadLine 历史预测 | 输入部分命令后，灰色文字实时预测完整命令，按 `→` 接受 |
|
||
| Layer 2 | Tab 菜单补全 | 按 `Tab` 弹出候选菜单，上下键选择，`Enter` 确认 |
|
||
| Layer 3 | posh-git 补全 | 为 `git` 命令提供子命令、分支名、远程名等补全 |
|
||
| Layer 4 | PSFzf 模糊搜索 | `Ctrl+R` 调出交互式历史命令搜索窗口，支持模糊匹配 |
|
||
|
||
### 快捷键速查
|
||
|
||
| 快捷键 | 功能 | PS5.1 | PS7+ |
|
||
|--------|------|-------|------|
|
||
| `→` | 接受行内预测 | ✅ | ✅ |
|
||
| `Tab` | 菜单补全，循环切换候选 | ✅ | ✅ |
|
||
| `Shift+Tab` | 反向切换候选 | ✅ | ✅ |
|
||
| `Ctrl+Space` | 显示所有候选项 | ✅ | ✅ |
|
||
| `↑ / ↓` | 按前缀过滤历史记录 | ✅ | ✅ |
|
||
| `Ctrl+R` | fzf 模糊历史搜索 | ✅ | ✅ |
|
||
| `Ctrl+T` | fzf 模糊文件查找 | ✅ | ✅ |
|
||
| `F2` | 切换 InlineView / ListView | ❌ | ✅ |
|
||
|
||
### 版本功能对照
|
||
|
||
| 功能 | PS5.1 | PS7+ | 说明 |
|
||
|------|-------|------|------|
|
||
| `PredictionSource History` | ✅ | ✅ | 基于历史命令预测 |
|
||
| `PredictionSource HistoryAndPlugin` | ❌ | ✅ | 额外加入插件预测源 |
|
||
| `PredictionViewStyle InlineView` | ✅ | ✅ | 行内灰字预测 |
|
||
| `PredictionViewStyle ListView` | ❌ | ✅ | 下拉候选列表 |
|
||
| `F2` 切换预测视图 | ❌ | ✅ | 实时切换两种视图 |
|
||
| PSReadLine 最高版本 | 2.3.x | 最新版 | 安装时需注意 |
|
||
| posh-git | ✅ | ✅ | 版本一致 |
|
||
| PSFzf | ✅ | ✅ | 版本一致 |
|
||
| WinGet 补全 | ✅ | ✅ | 编码处理略有差异 |
|
||
| Starship 钩子 | ✅ | ✅ | 函数名一致 |
|
||
| 动态窗口标题 | ✅ | ✅ | 实现方式一致 |
|
||
|
||
> PS5.1 缺少的 `ListView` 和 `HistoryAndPlugin` 可通过 PSFzf 的 `Ctrl+R` 模糊搜索弥补，日常体验差距不大。
|
||
|
||
### 常见问题
|
||
|
||
#### 执行 `. $PROFILE` 报执行策略错误
|
||
|
||
```powershell
|
||
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
|
||
```
|
||
|
||
#### 模块安装报 NuGet 错误
|
||
|
||
```powershell
|
||
Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force
|
||
```
|
||
|
||
#### PSReadLine 安装后不生效
|
||
|
||
PS5.1 系统自带一个旧版 PSReadLine，新版安装在用户目录下，需确认加载的是新版：
|
||
|
||
```powershell
|
||
Get-Module PSReadLine | Select-Object Name, Version, Path
|
||
# Path 应包含 CurrentUser 路径，而非 System32
|
||
```
|
||
|
||
如果仍加载旧版，在 Profile 最顶部显式指定：
|
||
|
||
```powershell
|
||
Remove-Module PSReadLine -ErrorAction SilentlyContinue
|
||
Import-Module PSReadLine -RequiredVersion 2.3.4
|
||
```
|
||
|
||
#### fzf / PSFzf 的 Ctrl+R 不弹出窗口
|
||
|
||
确认 fzf 本体已安装且在 PATH 中：
|
||
|
||
```powershell
|
||
fzf --version
|
||
```
|
||
|
||
如果命令不存在，重新安装并重启终端：
|
||
|
||
```powershell
|
||
winget install junegunn.fzf
|
||
```
|
||
|
||
#### 窗口标题不更新
|
||
|
||
确认 `Invoke-Starship-PreCommand` 函数定义在 `Invoke-Expression (&starship init powershell)` **之前**，因为 Starship init 会注册对该钩子的调用，函数本身需要提前存在。
|
||
|
||
#### posh-git 导致启动变慢
|
||
|
||
posh-git 在大型仓库中可能扫描较慢，可设置跳过未跟踪文件统计：
|
||
|
||
```powershell
|
||
$GitPromptSettings.EnableFileStatus = $false
|
||
```
|
||
|
||
## 编辑oh-my-posh配置文件
|
||
|
||
打开**PowerShell**终端，执行以下命令编辑配置文件 `code $PROFILE`：
|
||
|
||
```powershell
|
||
Set-PSReadLineKeyHandler -Key Tab -Function MenuComplete #Tab键会出现自动补全菜单
|
||
Set-PSReadlineKeyHandler -Key UpArrow -Function HistorySearchBackward
|
||
Set-PSReadlineKeyHandler -Key DownArrow -Function HistorySearchForward #上下方向键箭头，搜索历史中进行自动补全
|
||
|
||
oh-my-posh init pwsh --config "$env:POSH_THEMES_PATH/jandedobbeleer.omp.json" | Invoke-Expression
|
||
Import-Module posh-git # git的自动补全
|
||
```
|
||
|
||
# 文件
|
||
|
||
## 新建文件
|
||
|
||
```powershell
|
||
New-Item <文件名>.<扩展名后缀>
|
||
New-Item my.ini
|
||
```
|
||
|
||
## 删除文件
|
||
|
||
```powershell
|
||
Remove-Item <文件名>.<扩展名后缀>
|
||
Remove-Item my.ini
|
||
```
|
||
|
||
## 对文件添加内容
|
||
|
||
```powershell
|
||
Set-Content <文件名>.<扩展名后缀> -value "<内容>"
|
||
Set-Content my.ini -value ""
|
||
```
|
||
|
||
## 新建文件夹
|
||
|
||
```powershell
|
||
New-Item data -ItemType Directory
|
||
```
|
||
|
||
# 目录
|
||
|
||
|
||
|
||
# 查询版本
|
||
|
||
```powershell
|
||
$PSVersionTable
|
||
```
|
||
|
||
在输出的信息中，查看 **`PSVersion`** 这一行。
|
||
|
||
**示例输出解读：**
|
||
|
||
- **Major**: 主版本号（如 5 或 7）。
|
||
- **Minor**: 次版本号。
|
||
- 如果显示 `5.1.xxxxx`，这是 Windows 自带的 **Windows PowerShell**。
|
||
- 如果显示 `7.x.x`，这是跨平台的 **PowerShell (Core)**。
|
||
|
||
仅查看版本号（简洁）
|
||
|
||
如果你不需要其他详细信息，只想看版本号，可以使用这个命令：
|
||
|
||
```powershell
|
||
$PSVersionTable.PSVersion
|
||
```
|
||
|
||
或者使用宿主查询命令（虽然通常一致，但在某些特殊宿主环境下可能不同）：
|
||
|
||
```powershell
|
||
(Get-Host).Version
|
||
```
|
||
|
||
从 CMD (命令提示符) 查看
|
||
|
||
如果你当前在 CMD 窗口，不想进入 PowerShell 也能查看：
|
||
|
||
```powershell
|
||
powershell -command "$PSVersionTable.PSVersion"
|
||
```
|
||
|
||
### 补充说明：常见的两个主要版本
|
||
|
||
- **Windows PowerShell 5.1**：这是 Windows 10 和 Windows 11 默认自带的版本（蓝色背景图标）。微软已不再为其开发新功能，仅进行维护。
|
||
- **PowerShell 7.x**：这是微软目前主推的跨平台版本（黑色背景图标），性能更强，功能更多。
|
||
|
||
# 做 sudo 命令
|
||
|
||
在Windows系统上sudo对应的就是管理员权限了。
|
||
|
||
一般使用Powershell时，并不会管理员启动，当执行需要权限的命令（比如net start mysql），就需要以管理员打开新的窗口。
|
||
|
||
为了一步到位，这里给powershell创建一个`alias` -> `sudo` 来运行需要管理员权限的命令。
|
||
|
||
在文档目录中(在`powershell`执行`$profile`即可输出此文件路径)，新建文件夹`WindowsPowerShell`，新建文件`Microsoft.PowerShell_profile.ps1`。
|
||
|
||
> 此文件是在启动Powershell时执行的脚本。set-alias 在退出后就会失效，所以放到启动脚本中。
|
||
|
||
追加如下代码,**然后重启Powershell窗口。**
|
||
|
||
```text
|
||
function _sudo {
|
||
$ss = "$args ; pause"
|
||
Start-Process powershell -Verb runAs -ArgumentList $ss
|
||
}
|
||
set-alias -name sudo -value _sudo
|
||
```
|
||
|
||
保存后发现无法加载，因为默认不加载外部脚本，管理员权限下 powershell 运行：
|
||
|
||
```text
|
||
set-ExecutionPolicy RemoteSigned
|
||
```
|
||
|
||
# 实用脚本
|
||
|
||
## 自动延长VS社区版过期时间
|
||
|
||
> 该脚本作用为 自动检查VS社区版是否在一天内过期，如是则自动延长30天
|
||
>
|
||
> 需事先从Github上Clone开源项目[beatcracker/VSCELicense: PowerShell module to get and set Visual Studio Community Edition license expiration date in registry (github.com)](https://github.com/beatcracker/VSCELicense)
|
||
>
|
||
> 然后放置在指定目录，并解除脚本执行限制，以管理员身份执行如下命令：
|
||
>
|
||
> ```powershell
|
||
> Set-ExecutionPolicy RemoteSigned
|
||
> ```
|

>
|

可结合任务计划程序进行使用，免去手动执行的烦恼
|
||
|
||
|
||
|
||
### 🧩 步骤 1：打开任务计划程序
|
||
|
||
1. 按下 `Win + R`，输入 `taskschd.msc`，回车。
|
||
2. 在左侧的“任务计划程序库”中，右键选择“创建任务”。
|
||
|
||
### 🧩 步骤 2：设置任务基本信息
|
||
|
||
- 常规
|
||
|
||
选项卡：
|
||
|
||
- 名称：例如 `Check-VS-LicenseExpiration`
|
||
- 描述（可选）：每天早上 7 点检查许可证过期状态
|
