./run.sh copy "folder/with/files/tabDnsRouters" "dnsRouter -> healthCollector"
This will change all the files, folders and content with the word "dnsRouter" to "healthCollector".
./run.sh rename "folder/with/files/tabDnsRouters" "dnsRouter -> healthCollector"
This will do the same, but to a new folder that will be copied from the source.
