The easy way to write a script to do some is to figure out how to do it manually first and then build a script that incorporates that manual command (or set of commands) and puts it (or them) in a script with a little bit of boilerplate in a loop (since you want to repeat the process for a set of servers instead of just doing it for one server).
If you can't show us the exact command(s) you would type into
ksh to copy files from your source folder to a destination folder on one of your target servers, and a sample of your configuration file format including at least the configuration details for the target server used in your example showing the commands you would use to manually copy files to that server, we can't help you automate your manual process.
Note that this is the UNIX and Linux Forums. My understanding is that
winscp is intended for use on Windows systems; not UNIX and UNIX-like systems. When you need help with a script to run on Windows, you need to clearly state that up front. Are your destination servers also running Windows? (If not, what operating systems are they running.)
