works
作品
scp localhost:"f/a\ b\ c" .
scp localhost:'f/a\ b\ c' .
does not work
不起作用
scp localhost:'f/a b c' .
The reason is that the string is interpreted by the shell before the path is passed to the scp command. So when it gets to the remote the remote is looking for a string with unescaped quotes and it fails
原因是在将路径传递给 scp 命令之前，shell 会解释该字符串。因此，当它到达遥控器时，遥控器正在寻找带有未转义引号的字符串，但它失败了
To see this in action, start a shell with the -vx options ie bash -vxand it will display the interpolated version of the command as it runs it.
要查看此操作，请使用 -vx 选项 ie 启动 shell，bash -vx它将在运行时显示命令的内插版本。

Basically you need to escape it twice, because it's escaped locally and then on the remote end.
基本上你需要转义它两次，因为它在本地转义，然后在远程端转义。
There are a couple of options you can do (in bash):
您可以执行以下几个选项（在 bash 中）：
scp [email protected]:"'web/tmp/Master File 18 10 13.xls'" .
scp [email protected]:"web/tmp/Master\ File\ 18\ 10\ 13.xls" .
scp [email protected]:web/tmp/Master\\ File\\ 18\\ 10\\ 13.xls .

Also you can do something like:
您也可以执行以下操作：
scp foo@bar:"\"apath/with spaces in it/\""
The first level of quotes will be interpreted by scp and then the second level of quotes will preserve the spaces.
第一级引号将由 scp 解释，然后第二级引号将保留空格。

I had huge difficulty getting this to work for a shell variablecontaining a filename with whitespace. For some reason using
我很难让它适用于包含带有空格的文件名的shell 变量。由于某种原因使用
file="foo bar/baz"
scp [email protected]:"'$file'"
as in @Adrian's answer seems to fail.
正如@Adrian 的回答似乎失败了。
Turns out that what works best is using a parameter expansion to to prepend backslashes to the whitespace, as follows.
事实证明，最好的方法是使用参数扩展来将反斜杠添加到 whitespace，如下所示。
file="foo bar/baz"
file="${file//\ /\\ }"
scp [email protected]:"$file"

Use 3 backslashes to escape spaces in names of directories:
使用 3 个反斜杠来转义目录名称中的空格：
scp user@host:/path/to/directory\\\ with\\\ spaces/file ~/Downloads
scp user@host:/path/to/directory\\\ with\\\ spaces/file ~/Downloads
should copy to your Downloadsdirectory the filefrom the remote directory called directory with spaces.
应该从名为 的远程目录复制到您的Downloads目录。filedirectory with spaces

Sorry for using this Linux question to put this tip for Powershell on Windows 10: the space char escaping with backslashes or surrounding with quotes didn't work for me in this case. Not efficient, but I solved it using the "?" char instead:
很抱歉使用这个 Linux 问题将这个提示用于 Windows 10 上的 Powershell：在这种情况下，用反斜杠转义或用引号包围的空格字符对我不起作用。效率不高，但我使用“？”解决了它 字符代替：
for the file "tasks.txt Jun-22.bkp" I downloaded it using "tasks.txt?Jun-22.bkp"
对于文件“tasks.txt Jun-22.bkp”，我使用“tasks.txt?Jun-22.bkp”下载了它
