Powershell 产生不完整的结果。从加入 cmdlet 中删除显示的逗号
Powershell produces incomplete results. Removing displayed commas from join cmdlet
我对脚本编写很陌生，希望有人能提供一些建议。
我亲自创建了一个对项目管理有用的 PowerShell 脚本。该脚本分析文件路径以确定它是否太长，并检查文件名是否少于 50 个字符。此外，它确保除其他事项外没有非法字符。所有结果最初都打印到文本文件中。
在 PowerShell 脚本中，我最初让步骤 1、2 和 3-9 生成 3 个单独的文档。但最终，我决定将所有步骤写入一个文本文件。在最后一步中，然后导入文本文件以创建 CSV。然后文件路径按字母顺序排序，并合并返回 2 个不同结果的所有文件路径。最终，用户将参考此 CSV，以便在他们的媒体存档之前手动更正任何错误。
这是我遇到的问题。
从步骤 1 到 9，生成的文本文件不完整。当我检查文本文件时，它在写入路径的过程中停止了。我还注意到在步骤 10 中创建的 CSV 也有不完整的结果。

在第 10 步中，我使用了 join cmdlet 以合并 CSV 中的结果。所以，如果一个文件名有两个不同的结果，我想将结果合并到 1 行中。我使用逗号作为分隔符，但当我这样做时，它实际上在 CSV 中显示多个逗号。有没有办法防止显示逗号？

您不应该创建这样的临时 csv 文件，然后将其转换为 CSV，您可以使用 PSCustomObject 和 Export-Csv.
立即将其转换为 CSV
您创建 csv-like 临时文件的方式很容易弄乱逗号的数量，从而导致字段未对齐。
此外，我建议不要在 CSV 文件中使用逗号 headers（也许可以缩短它们，但这取决于您）。

如您所见，我更改了一些测试：
- 删除了正则表达式
-match 上的 (?i)，因为默认情况下是 case-insensitive
- 将
- 移到 [^-a-z0-9 _.] 等正则表达式的前面，否则它将被解释为正则表达式范围而不是减号本身
- 更改了隐藏文件的测试
