I use scp to upload files in a remote server. When the files already exist on the server I get a prompt like replace file? [y]es, [n]o, [A]ll, [N]one, [r]ename:
Due to the fact that I want to automate this procedure, I need to disable somehow this prompt, so there is no need for a middle man to answer the prompt and always overwrite the existing files.
Update: Actually the message was prompted by the uzip command I was using after I transfer the files. In order to automatically overwrite the files I did unzip -o name_of_zip_file.zip. But the rsync command is also better solution than the scp, because it also encypts and compress the data while transfering them, if you use the appropriate wildcards.
You can think of using Rsync, Complete reference can be found here
