我对脚本编写很陌生，希望有人能给我一些建议。
我自己创建了一个PowerShell脚本，它将对项目管理有用。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，它还确保了在其他方面没有非法字符。所有结果最初都打印到一个文本文件中。
在PowerShell脚本中，我最初让步骤1、2和3-9生成3个独立的文档。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，导入文本文件以创建CSV。然后按字母顺序对文件路径进行排序，并合并返回2个不同结果的任何文件路径。最终，用户将参考此CSV，以便在存档介质之前手动更正任何错误。
以下是我遇到的问题。
-
从步骤1-9开始，生成的文本文件不完整。当我检查文本文件时，它会在写入路径的过程中停止。我还注意到，在步骤10中创建的CSV也有不完整的结果
在此处输入图像描述 -
在步骤10中，我使用join cmdlet将结果合并到CSV中。所以，如果一个文件名有两个不同的结果，我想把结果合并成一行。我使用逗号作为分隔符，但当我这样做时，它实际上会在CSV中显示多个逗号。有没有办法防止逗号被显示

您不应该创建这样的临时csv文件，然后将其转换为csv，在那里您可以使用PSCustomObject和Export csv直接执行此操作
创建类似csv的临时文件的方式很容易混淆逗号的数量，从而导致字段错位。
此外，我建议不要在CSV标头中使用逗号(也许可以缩短它们，但这取决于您(。

正如你所看到的，我已经改变了一些测试：
- 删除了正则表达式
-match上的(?i)，因为默认情况下这是不区分大小写的 - 在像
[^-a-z0-9 _.]这样的正则表达式中将-移到前面，因为否则它将被解释为正则表达式范围，而不是减号字符本身 - 更改了隐藏文件的测试
