aws s3 cp "file_name.txt s3://"bucket_name"

If there is no bucket in the S3 then create it by using the command.

aws s3 mb s3://"bucket_name"

After creating it upload the created file in the bucket by using the command.

aws s3 cp "file_name.txt s3://"bucket_name"

After uploading the files go check your AWS console to verify it.
