Powershell 将新文件转换为 tiff

Powershell 将新文件转换为 tiff

我有一个由我编写的 powershell 脚本，它查看文件夹中新添加的文件，然后将这些文件移动到另一个文件夹，然后使用 ghostscript 将其转换为 .tif。之后，所有 .pdf 都会移动到 PDF 文件夹，所有 tiff 都会移动到 TIF 文件夹。完成后，它会将日志条目写入 txt 文件。放入 Import 文件夹的任何新文件都会触发此脚本再次运行。

我遇到的问题：

  1. 转换后的 Tiff 在文件名前面有“TIF”，我不想要这个，只想和创建它的 pdf 同名。
  2. 当转换第二个文件时，它会创建最后一个转换文件的副本并将其粘贴在根文件夹中。不知道为什么会这样。但我只想要一份 tif 副本，并将其放在 TIF 文件夹中。

希望有人能告诉我我做错了什么！

代码：

   $watcher = New-Object System.IO.FileSystemWatcher
    $watcher.Path = "C:\Folder\Import"

对于问题/答案的编辑，我深表歉意。

这是工作脚本。它有相当多的更改，但执行效果符合要求。在开发中期，我被要求将 .pdf 更改为 .tiff 再更改为 .txt 再更改为 .jpg。这个过程仍然运行良好，您只需修改 Ghost 脚本部分即可获得所需的输出类型。

由于得到了其他线程的大量帮助，因此该脚本的相当一部分内容是由许多不同的人拼凑起来的。

所需组件：

  1. 电源外壳
  2. CutePDF 作家
  3. GhostScript

此脚本的作用如下：

  1. 扫描文件夹并记录文件
  2. 将 .txt 文件移动到根文件夹进行处理
  3. 使用 CutePDF Writer 将 .txt 文件打印为 .pdf
  4. 使用 Ghostscript 将 .pdf 文件转换为 .jpg
  5. 将 .pdf、.jpg 和 .txt 文件移动到单独的文件夹
  6. 删除所有 .pdf
  7. 如果发现更改，则开始对“处理”文件夹进行更改扫描并再次运行脚本。

我将其转换为 .exe 并使用 NSSM 将其设置为始终运行的服务。
