后悔药系列
放脚本
cat /tmp/rm.sh
#!/bin/bash
mkdir -p /tmp/.trash
TRASH_DIR="/tmp/.trash"
for i in $*; do
#定义秒时间戳
STAMP=`date +%s`
#得到文件名称(非文件夹)，参考man basename
fileName=`basename $i`
#将输入的参数，对应文件mv至.trash目录，文件后缀，为当前的时间戳
mv $i $TRASH_DIR/$fileName.$STAMP
echo -e "\033[31m $1 >>>>> /tmp/.trash \033[0m"
done
改环境变量
cat >> /root/.bashrc <<EOF
alias rm="sh /tmp/rm.sh" #这是我脚本放的位置
EOF
source /root/.bashrc ## 生效
测试
[root@pa2 tmp]# touch 666
[root@pa2 tmp]# rm 666
666 >>>>> /tmp/.trash
[root@pa2 tmp]# ll .trash/
total 12
-rw-r--r-- 1 root root 0 May 16 18:17 666.1526465830 ##在这
-rw-r--r-- 1 root root 73 May 15 17:20 lua_JZ2h4i.1526465674
drwxr-xr-x 3 root root 4096 May 10 17:22 pear.1526465758

清理脚本+定时任务
[root@pa2 tmp]# cat clear.sh
#!/bin/bash
find /tmp/.trash -mtime +3 -exec \rm {} \;
加入定时任务,我知道你会的
删根测试？
[root@local ~]# rm /*
/bin >>>>> /tmp/.trash
/tmp/rm.sh: line 7: date: command not found
/tmp/rm.sh: line 9: basename: command not found
/tmp/rm.sh: line 11: mv: command not found
/bin >>>>> /tmp/.trash
/tmp/rm.sh: line 7: date: command not found
/tmp/rm.sh: line 9: basename: command not found
/tmp/rm.sh: line 11: mv: command not found
/bin >>>>> /tmp/.trash
/tmp/rm.sh: line 7: date: command not found
/tmp/rm.sh: line 9: basename: command not found
/tmp/rm.sh: line 11: mv: command not found
/bin >>>>> /tmp/.trash
················省略······················
[root@local ~]# cd /tmp/
[root@local tmp]# ll -a
-bash: /bin/ls: No such file or directory #一下回到解放前
改别名系列
echo "alias rm='No use rm command'" >> /etc/profile
vim /root/.bashrc #注释掉想要改别名的那一行
source /etc/profile #生效
结果
实验证明，你要删根，谁都阻止不了
但是，又不能否认我们这个脚本的作用，抛开环境谈作用都是扯淡
