for f in **/*.ts; do mv “$f” “${f%.ts}.js”; done

This will keep the first instance of a duplicate:

sort for_db.txt | uniq > for_db_no_duplicates_2.txt

This will remove all duplicates (including the first occurence):

sort for_db.txt | uniq -u > for_db_no_duplicates_2.txt

Replace <PortNumber> with the port that is already in use

$ lsof -i :<PortNumber>

Find the PID in the result from above and replace <PID> with that.

$ kill -9 <PID>
