PowerShell:尽管使用 Windows 资源管理器执行相同的过程，但 Copy-Item 仍失败 [英] PowerShell: Copy-Item fails despite the same process working with Windows Explorer

问题描述

我有一个脚本需要定期(每小时)复制文件.我可以使用 Windows 资源管理器打开源文件夹和目标文件夹，然后毫无问题地复制文件.

I have a script that needs to copy files on a regular basis (every hour). I can open the source and destination folder using windows explorer and copy the file without issue.

但是，如果我在 PowerShell 中尝试相同的操作，我会收到访问路径被拒绝"错误.我已经检查了共享的权限并且我拥有完全访问权限.为什么这会通过 PowerShell 失败?

However, if I try the same thing in PowerShell I get an Access to the path is denied error. I've checked the permissions on the share and I have full access. Why does this fail through PowerShell?

复制项目命令:

Copy-Item \\idmststtrm2\tns_admin$\tnsnames.ora -Destination \\bts13r2b\tnsnames -Force

错误:

Copy-Item : Access to the path '\\bts13r2b\tnsnames\tnsnames.ora' is denied.

当我对目标路径执行 Get-ChildItem 时，我能够看到文件夹内容.

When I execute a Get-ChildItem against the destination path, I'm able to see the folder contents.

get-item 的结果:

尝试使用 xcopy:

Tried using xcopy:

xcopy \\idmststtrm2\tns_admin$\tnsnames.ora \\bts13r2b\tnsnames\tnsnames.ora

Access is denied.

推荐答案

此问题是由于写入网络共享的权限所致.虽然共享权限设置正确，但缺少 NTFS 权限.系统管理员需要确保两组权限都允许帐户写入文件夹.一旦正确更新，脚本就能够执行到网络共享的复制.

This problem is due to permissions writing to a network share. While the share permissions were set correctly, the NTFS permissions were missing. A system administrator will need to ensure both sets of permissions allow for the account to write to the folder. Once this was updated correctly the script was able to perform a copy to the network share.
