linux - How to copy files from dir and append date to filename?

Question

I'm trying to copy files from one directory to another and append current date to this filename. The script look like this

#!/bin/bash

echo 'Move to homedir'
cd $HOME

echo 'Copy .txt files'
NOW=$(date +"%d%m%Y")

for FILENAME in *.txt
do
        cp "${FILENAME}" "/newdir/${FILENAME}${NOW}"
done

This generates an error because date is appended after file extension, like this

file1.txt10082013

How to avoid that?

尝试提取扩展名并重命名文件：

NAME="${FILENAME%.*}"
EXT="${FILENAME##*.}"

cp "${FILENAME}" "/newdir/${NAME}${NOW}.${EXT}"
