openssh bugs - Jul 2006 - [Bug 1205] scp back-slash escaping of spaces ignored after username@hostname: tag

http://bugzilla.mindrot.org/show_bug.cgi?id=1205

           Summary: scp back-slash escaping of spaces ignored after
                    username at hostname: tag
           Product: Portable OpenSSH
           Version: 4.3p2
          Platform: ix86
        OS/Version: Linux
            Status: NEW
          Keywords: low-hanging-fruit
          Severity: normal
          Priority: P3
         Component: scp
        AssignedTo: bitbucket at mindrot.org
        ReportedBy: dcescato at ee.ethz.ch


Back-slash escaping of spaces works when accessing local files:

[genie at homeland ~]$ echo "hello" > spa\ ce
[genie at homeland ~]$ ls -l spa\ ce
-rw-rw-r-- 1 genie genie 6 Jul  3 14:58 spa ce
[genie at homeland ~]$  scp /home/genie/spa\ ce
bugzilla at armageddon.ethz.ch:/home/bugzilla
spa ce                                                   100%    6    
0.0KB/s   00:00


The file is actually on the remote machine:

[bugzilla at armageddon ~]$ ls -l spa\ ce
-rw-rw-r-- 1 bugzilla bugzilla 6 Jul  3 14:58 spa ce


If I now try to copy the file from the remote machine, I get the
following error:

[genie at homeland ~]$ rm spa\ ce
[genie at homeland ~]$ scp bugzilla at armageddon.ethz.ch:/home/bugzilla/spa\
ce . 
scp: /home/bugzilla/spa: No such file or directory
scp: ce: No such file or directory


Hence, back-slash escaping of spaces after a "username at hostname:"
tag
seems to be ignored.

I'd say that this is a feature rather than a bug. The path is again
shell expanded on the remote machine.
This will work:
scp "<host>:<path>/spa\\ ce" .

Sorry - we can't fix this: it is a 20+ year old limitation of rcp that
scp has inherited and changing the behaviour of scp would break many
people's working scripts.
