Python scp复制文件，文件名中带有空格 [英] Python scp copy file with spaces in filename

问题描述

我正在尝试使用scp在本地网络中复制文件. 它可以与没有空格的文件名一起很好地工作，但是会崩溃. 我试图用"\"代替"，因为这

I'm trying to copy files in local network with scp. It's working well with filenames without spaces, but it crash with. I've tried to replace " " with "\ " as this exemple, but it don't work. Here is my code:

def connection(locals):
         a = (int(re.search(br'(\d+)%$', locals['child'].after).group(1)))
         print a
         perc = (Decimal(a)/100)
         print (type(perc)), perc
         while gtk.events_pending():
             gtk.main_iteration()
         FileCopy.pbar.set_text("Copy of the file in the Pi...   " + str(a) + "%")
         while gtk.events_pending():
             gtk.main_iteration()
         FileCopy.pbar.set_fraction(perc)

file_pc = "/home/guillaume/folder/a very large name of file with space .smthg"
file_pi = "pi@192.168.X.X:/home/pi/folder/a very large name of file with space .smthg"

if " " in file_pc:
   file_pc = fichier_pc.replace(" ", '\\\ ')   # tried '\\ ' or '\ '
   file_pi = fichier_pi.replace(" ", '\\\ ')   # but no way
else:
   pass
command = "scp %s %s" % tuple(map(pipes.quote, [file_pc, file_pi]))
pexpect.run(command, events={r'\d+%': connection}) # this command is using to get the %

如何解决此问题? 谢谢

How can I fix this problem ? Thanks

推荐答案

您可以将本地文件file_pc保持不变(pipes.quote将转义空格).远程文件应更改:

You may keep local file file_pc as is (pipes.quote will escape the spaces). The remote file should be changed:

import pipes

file_pi = 'pi@192.168.X.X:/home/pi/folder/file with space.smth'
host, colon, path = file_pi.partition(':')
assert colon
file_pi = host + colon + pipes.quote(path)

，即user@host:/path/with space应该更改为user@host:'/path/with space'
