Your needs are not very clear, nor the scope of what you are looking for. A simple bash script can do that
Code:
for EXEC in `find /home/kde-devel/ -iname "*.exe"`; do
mysql -u user -p password -q database -e "INSERT INTO TABLE_NAME (exec) VALUES ('$EXEC');"
done
This one is if you want to run it from a live-cd. If you want to scan the network, then use nmap in a script. We don't know what you want to do, so we can't really help you.
