尝试使用来自 PS 中的 nitado 服务器的文件掩码 ftp 一些文件，我错过了什么吗？

Question

I have the following in a ps1 script and I am connecting over ftp using winscp to a nitrado server with the goal of copying the folder called backups and the contents over to my pc. The issue I face is when I run the following it just returns the whole of the minecraftbukkit folder almost as if it ignores the mask other than '*' and just returns it all. I have tried using a mask of "backups/" however this then returns nothing and in the log output it says File "/minecraftbukkit" excluded from transfer.

I have tried this on my personal linux server and it seemed to work so is this some issue based on the nitrado service? or possibly their linux server is missing a feature that is needed or something. I am open to any suggestions on how to make this work as intended. Thanks in advance.

In terms of folder structure this is it just a regular bukkit layout and I am trying to pull the backups folder as shown:

Answer 1

If you want to download backups specifically, do it explicitly:

$folderPath2 = '/minecraftbukkit/backups/*'

---

If you point was to make the "filemask" variable, your problem is that your are giving WinSCP conflicting masks. You are telling it to download everything that has name minecraftbukkit and backups at the same time. So it does not download anything.

If you want to tell WinSCP to apply the mask to files in minecraftbukkit and not to the minecraftbukkit directly, you need to add a slash to the path. Or to make it even more obvious, add /* :

$folderPath2 = '/minecraftbukkit/*'

As the documentation for theremotePath parameter says:

Full path to remote directory followed by slash and wildcard to select files or subdirectories to download. To download all files in a directory, use mask * .
