string - Powershell计数文件中的行

Question

问题
Measure-Object -Line行为不一致，并且在尝试读取文件时未返回正确的行数。

使用.Count似乎可以解决此特定问题，但又不能保持一致，因为在处理字符串时，它的工作方式不同。

题

如何始终从文本或文件中获取正确的行数？

MWE

$File       = ".\test.ini"
$FileContent  = Get-Content $File
$Content =
"    # 1
    [2]
    3

    5

    [7]

    ; 9
"

$EndOfFile    = $FileContent | Measure-Object -Line
$EndOfText    = $Content | Measure-Object -Line

Write-Output "Lines from file: $($EndOfFile.Lines)"
Write-Output "Lines from text: $($EndOfText.Lines)"
Write-Output "Count from file: $($FileContent.Count)"
Write-Output "Count from text: $($Content.Count)"

注意: test.ini的内容与 $Content变量完全相同。

输出量

Lines from file: 6
Lines from text: 9
Count from file: 9
Count from text: 1

Answer 1

的确，@ TheIncorrigible1在说什么。要在示例中做到一致，您必须采用以下方式:

$File       = ".\test.ini"
$FileContent  = Get-Content $File

$Content = @(
    "# 1",
    "[2]",
    "3",
    "",
    "5",
    ""
    "[7]",
    ""
    "; 9"
)

$EndOfFile    = $FileContent | Measure-Object -Line
$EndOfText    = $Content | Measure-Object -Line

Write-Output "Lines from file: $($EndOfFile.Lines)"
Write-Output "Lines from text: $($EndOfText.Lines)"
Write-Output "Count from file: $($FileContent.Count)"
Write-Output "Count from text: $($Content.Count)"

一致的输出:

Lines from file: 6
Lines from text: 6
Count from file: 9
Count from text: 9
