Hi, I'm using smbclient to upload to a share with guest write access; smbclient //server/share -U guest -c 'put file' I would like to prevent the put succeeding if the guest user already uploaded a file with the same name but can't see a smbclient option for this. Is there a way to set this? I'm also thinking it should be considered unsafe default behaviour to overwrite the file. Cheers Tristan
