无法识别函数 Get-IniContent - PowerShell 中的 INI 文件支持

Question

我想编辑INI文件的值。我使用这个脚本，但它给我错误。

Get-IniContent : The term 'Get-IniContent' is not recognized as the name of a 
cmdlet, function, script file, or operable program.

我在 c:\Users\file.ini 处的 INI 文件的内容：

[XXX]
AB=23
BC=34

读取更新脚本内容：

# Read the content of an *.ini file into a (nested) hashtable.
$ini = Get-IniContent "C:\Users\file.ini"

# Update the 'AB' entry in section [XXX] in-memory.
$ini["XXX"]["AB"] = "12"  

# Write the updated content back to the *.ini file.
$ini | Out-IniFile -FilePath "C:\Users\file.ini -Force"

Answer 1

JeroenMostert在评论中提供了关键指针：

从 v7 开始，PowerShell 具有没有用于处理 INI 文件的内置 cmdlet (*.ini)，但是引入这样的 cmdlet is being discussed on GitHub.

Get-IniContent 和 Out-IniFile 是 third-party PSIni module, available from the PowerShell Gallery.

附带的高级函数（类似于 cmdlet 的函数）

在 PowerShell v5 或更高版本中，PowerShellGet 模块^[1]，安装就像:

Install-Module -Scope CurrentUser PsIni

^{如果您省略 -Scope CurrentUser，您将为所有用户安装该模块，但这样做需要运行管理权限.}

默认情况下（未设置）$PSModuleAutoLoadingPreference，此模块随后会根据需要自动加载到尝试调用模块命令之一的会话中，比如Get-IniContent.

这是一个完整的、自包含的示例，它练习了 PsIni 模块的核心功能：

按需安装模块
使用 Out-IniFile 从嵌套的有序哈希表中从头开始创建示例 *.ini 文件。
使用 Get-IniContent 从磁盘读取文件到（新的）嵌套有序哈希表中
修改和删除条目
用Out-IniFile

注意：假设 Install-Module 可用，即安装了 PowerShellGet 模块，并且运行机器在线并允许从 https://www.powershellgallery.com/。

# Import the PsIni module.
# If necessary, install it first, for the current user.
$ErrorActionPreference = 'Stop' # Abort, if something unexpectedly goes wrong.
try {
  Import-Module PsIni
} catch {
  Install-Module -Scope CurrentUser PsIni
  Import-Module PsIni
}

# Create an ordered hashtable that is the in-memory representation of the
# sample *.ini file from the question, with a second section added.
$iniFileContent = [ordered] @{
  # 'XXX' is the section name.
  # The nested hashtable contains that section's entries.
  XXX = [ordered] @{  
    # IMPORTANT: 
    #  * The PsIni module only supports STRING values.
    #  * While you can assign values of different types in-memory, they are
    #    CONVERTED TO STRINGS with .ToString() and READ AS STRINGS later
    #    by Get-IniContent.
    #  * In v3+, PSIni now supports values in *.ini files that have 
    #    embedded quoting - e.g., `AB = "23"` as a raw line - which is
    #    (sensibly) *stripped* on reading the values.
    AB = '23'
    BC = '34'
  }
  # Create a 2nd section, named 'YYY', with entries 'yin' and 'yang'
  YYY = [ordered] @{
    yin = 'foo'
    yang = 'none'
  }
}

# Use Out-IniFile to create file 'file.ini' in the current dir.
# * Default encoding is UTF-8 (with BOM in Windows PowerShell, without BOM
#   in PowerShell Core)
# * Use -Encoding to override, but note that
#   Get-IniContent has no matching -Encoding parameter, so the encoding you use
#   must be detectable by PowerShell in the absence of explicit information.
# * CAVEAT: -Force is only needed if an existing file must be overwritten.
#           I'm using it here so you can run the sample code repeatedly without
#           failure, but in general you should only use it if you want to
#           blindly replace an existing file - such as after having modified
#           the in-memory representation of an *.ini file and wanting to
#           write the modifications back to disk - see below.
$iniFileContent | Out-IniFile -Force file.ini

# Read the file back into a (new) ordered hashtable 
$iniFileContent = Get-IniContent file.ini

# Modify the value of the [XXX] section's 'AB' entry.
$iniFileContent.XXX.AB = '12'

# Use the alternative *indexing syntax* (which is equivalent in most cases)
# to also modify the [YYY] section's 'yin' entry.
$iniFileContent['YYY']['yin'] = 'bar'

# Remove the 'yang' value from section [YYY]:
$iniFileContent.YYY.Remove('yang')

# Save the modified content back to the original file.
# Note that -Force is now *required* to signal the explicit intent to
# replace the existing file.
$iniFileContent | Out-IniFile -Force file.ini

# Double-check that modifying the values succeeded.
(Get-IniContent file.ini).XXX.AB # should output '12'
(Get-IniContent file.ini).YYY.yin # should output 'bar'

# Print the updated content of the INI file, which
# shows the updated values and the removal of 'yang' from [YYY].
"--- Contents of file.ini:"
Get-Content file.ini

运行以上应该会成功并输出以下内容，证明 *.ini 文件已成功创建、读回内存、修改并保存回磁盘：

12
bar
--- Contents of file.ini:
[XXX]
AB=12
BC=34
[YYY]
yin=bar

Answer 2

因为我是 powershell 的新手，当我读到这篇文章时 post 我首先想到我必须使用 cmdlet 来读写 Ini-Files。但是，没有必要。

$ini= [System.IO.File]::ReadAllText("c:\temp\test.ini")
[System.IO.File]::WriteAllText("c:\temp\test2.ini", $ini)

这也行...只是想分享 :)
