linux - 为什么这个文件没有下载到指定位置？

Question

我正在下载这个link中的文件.我使用的是 Ubuntu 12.04，我使用以下命令下载它。

wget -p /home/ubuadmin/CUDA http://developer.download.nvidia.com/compute/cuda/5_5/rel/installers/cuda_5.5.22_linux_32.run

下面是我的命令行输入和输出。

root@ubuserver3:/home/ubuadmin# wget -p /home/ubuadmin/CUDA http://developer.download.nvidia.com/compute/cuda/5_5/rel/installers/cuda_5.5.22_linux_32.run

它说下载已完成，但我在该文件夹中找不到该文件。我正在使用 PuTTY 远程访问此服务器，并使用 WinSCP 查看文件结构。出了什么问题？为什么下载了就不见了？

Answer 1

要设置目标文件夹，请使用-P(大写)而不是-p。

来自 man wget:

-P prefix

--directory-prefix=prefix

Set directory prefix to prefix. The directory prefix is the directory where all other files and subdirectories will be saved to, i.e. the top of the retrieval tree. The default is . (the current directory).
