打印脚本所在的 Windows 目录的树，并根据 .gitignore 文件排除某些文件夹

问：

我有这个完全由 ChatGPT 生成的 powershell 脚本，因为我对 powershell 一无所知。相反，我更喜欢 Bash。

显示树.ps1

# Get the base path of the script
$scriptPath = Split-Path -Parent $MyInvocation.MyCommand.Path
$basePath = (Get-Item $scriptPath).FullName

# Define the path to the .gitignore file
$gitIgnorePath = Join-Path $basePath ".gitignore"

# Check if the PSTree module is installed
if (-not (Get-Module -ListAvailable -Name PSTree)) {
  # Install the PSTree module if it's not installed
  Install-Module -Name PSTree -Scope CurrentUser -Force -AllowClobber
}

# Check if the .gitignore file exists
if (Test-Path $gitIgnorePath -PathType Leaf) {
  # Read the patterns from the .gitignore file and split into an array
  $excludePatterns = Get-Content $gitIgnorePath -ErrorAction SilentlyContinue | ForEach-Object { "$basePath\$_" }

  # Import the PSTree module
  Import-Module PSTree
  
  $tmpStdout = "tmp.txt"

  # Use the base path and exclude patterns in the Get-PSTree command
  Get-PSTree -Exclude $excludePatterns | Out-File $tmpStdout

  # Read the contents of the file
  $lines = Get-Content -Path $tmpStdout
  # Define the number of lines to skip from the beginning and end
  $headLength = 6   # Number of lines to skip from the beginning
  $tailLength = 2   # Number of lines to keep at the end
  # Filter the lines based on the specified criteria
  $lines[$headLength..($lines.Count - $tailLength - 1)] | Out-File $tmpStdout

  # Read the content of the input file
  $content = Get-Content $tmpStdout
  # Process each line, cutting the first 23 characters
  $content | ForEach-Object { $_.Substring(23) } | Out-File $tmpStdout
  Get-Content $tmpStdout
  Remove-Item $tmpStdout

}
else {
  Write-Host "No .gitignore file found."

  # Import the PSTree module without exclusion
  Import-Module PSTree
  Get-PSTree
}

它工作正常。它返回

cf-ztna-app
├── .gitignore
├── README.md
├── requirements.txt
├── show-tree.ps1
├── start-server.cmd
├── tmp.txt
└── src
    ├── main.py
    └── __init__.py

这是我的.gitignore：

.venv
.env

但正如你所看到的，我在高效的代码中使用临时文件来存储输出。我正在使用 .Out-File $tmpStdout

我为什么要这样做？因为我只想获取树输出，而不是来自命令外部模块（非内置）的任何开销或不必要的信息。Windows 中的内置命令未提供排除标志。PSTreetree

这是我不想期待的原始输出：

许多空行和不必要的信息。Source

回复 @SantiagoSquarzon ，它没有排除 .gitignore 的内容：
