您希望如何通知来源团队？
您可以尝试bash脚本，例如：

#!/bin/bash
SrcDir="s3://.../"
s3_files=$(aws s3 ls $SrcDir/ | awk '{print $4}')

# check if all the expected files are present:
echo "Checking for expected files in S3 bucket..."
for file in $(cat filelist.txt); 
do
    if [[ ! "$s3_files" =~ "$file" ]]; then
        echo "$file is missing from S3 bucket"
    fi
done

# check the size of files
echo "Checking size of the files..."
for file in $(cat filelist.txt); 
do
    size=$(aws s3 ls $SrcDir/$file | awk '{print $3}')
    if [[ $size -eq 0 ]]; then
        echo "$file size is 0 KB"
    fi
done
