sftp rename not over writing

shihabvk · May 9, 2007, 12:31am

Hi,
I have an sftp script :
put file1.txt file1.txt.cp
rename file1.txt.cp myfile.txt

But the problem is, if the file myfile.txt exists at the remote location, the sftp fails to overwrite. How do I make it over writing.

I am using ssh version
OpenSSH_4.1, OpenSSL 0.9.7e 25 Oct 2004
HP-UX Secure Shell-A.04.00.000, HP-UX Secure Shell version

Please help me

Thanks in advance
Shihab

I searched around on google and found this. From that doc,

draft-ietf-secsh-filexfer-02.txt:

Files (and directories) can be renamed using the SSH_FXP_RENAME
message. Its data is as follows:
uint32     id
string     oldpath
string     newpath
where `id' is the request identifier, `oldpath' is the name of an
existing file or directory, and `newpath' is the new name for the
file or directory. It is an error if there already exists a file
with the name specified by newpath. The server may also fail rename
requests in other situations, for example if `oldpath' and `newpath'
point to different file systems on the server.

Looks like that is how it is supposed to behave. Try removing the existing file before you call rename.

blowtorch is correct, this is expected behavior(it's by design), overcome this by removing the the existing file.
