我将 Putty 连接到两个不同的 Ubuntu 服务器(A 和 B)。我想通过 SFTP 将 A 传输到 B,并将get
B 目录中的所有文件传输到 A,然后在下载后立即删除 B 中的文件 - 这样只有 A 拥有这些文件。
如何get
在传输/下载成功后立即获取文件并删除文件?
答案1
您可以使用以下命令删除远程文件:
rm [path]
对于远程目录:
rmdir [path]
用实际路径、文件名或目录名替换[path]
。这也可以是您在普通终端中习惯使用的通配符。要递归获取目录,您可能需要标志-r
。
遗憾的是,没有命令可以将文件从 B 移动到 A,因此您需要将文件从 B 获取到 A,然后删除 B 上的文件。这意味着没有命令将获取和删除连接在一起。
要批量获取然后删除文件,您可以使用通配符。
示例(假设您的文件位于服务器 B 上的 XY 文件夹中):
# log into server A via putty/ssh
ssh user@A
# then sftp to B from A
sftp user@B
# now you will get a prompt for sftp which I will not
# repeat in the commands to follow
sftp>
# navigate to your local target directory on server A
lcd pathtotarget/
# navigate to your source directory on server B
cd XY
# get all the files from B to A
get *
# after the transfer is done you can go on and remove the files on B
cd ..
rmdir XY
# or if you want only the files being deleted
rm *
# quit your sftp session
quit
# log off from server A
logout
