Renaming multiple files using shell script-CodePudding

I have downloaded multiple files from different s3 buckets to a single folder on a linux vm. I want to rename only the *.gz files in the directory, preferably sequentially, using a script to something like FILE001_$(date ' %Y%m%d').csv.gz,FILE002_$(date ' %Y%m%d').csv.gz etc, before moving them to client's sftp server(existing process).

I tried using find . -name "*.csv.gz" -exec mv {} FILEd_$(date ' %Y%m%d').csv.gz from another post but get missing argument to -exec error. Any examples using rename or mv for the above task please?

Try something like this:

#! /bin/bash
declare -i i=0
for f in *.csv.gz; do
  : $((i  ))
  mv "$f" "$(printf "FILEd_%s.csv.gz" $i "$(date  %Y%m%d)")"
done
