一. 添加脚本：
[root@qll251 ~]# vim /bin/delete
1 #! /bin/bash
2 [ ! -d /.recycle ] && mkdir -v /.recycle && chmod 777 /.recycle
3
4 if [ $# -eq 0 ]; then
5 echo "Usage: delete file1 [file2 file3...]" && exit 6
6 fi
7
8 read -p "Are you sure you want to delete it? [Y/N]: " action
9 case $action in
10 y) ;;
11 Y) ;;
12 *) exit
13 esac
14
15 for file in $@; do
16 now=date +%Y-%m-%d-%H:%M:%S
17 newfile=basename $file
18 mv $file /.recycle/$newfile.$now && echo "$file is deleted!"
19 done
二. 修改别名
编辑~/.bashrc文件，增加一行
alias rm='sh /bin/delete'
添加可执行权限：
[root@qll251 ~]# chmod +x /bin/delete
三. 定时清空
执行crontab -e，设置每周执行清空回收站动作
0 0 * * 0 rm -rf /.recycle
