Answer 1

如果你有 PowerShell v3，试试这个单行：

(Get-Content file.txt -Raw) -replace '(?<=\w{16}\s).+' -replace '(?<= ) |\r?\n\s+'

Answer 2

现在它变得更有意义了。看看我最喜欢的文本解析工具switch -regex：

switch -regex -file foo.txt {
    '^(\d+)\s+(\S+)' {
        if ($s) { $s }
        $s = "$($Matches[1]) $($Matches[2])"
    }
    '^\s+(\S+)' { $s += " $($Matches[1])" }
}
if ($s) { $s }
