Linux防rm -rf之safe-rm

首先，都知道在linux中“rm -rf /”命令，今个咱就破它。

第一步 下载

[root@xuegod1 safe-rm-0.12]# wget https://launchpad.net/safe-rm/trunk/0.12/+download/safe-rm-0.12.tar.gz

第二部 解压

[root@xuegod1 safe-rm-0.12]# tar -xf safe-rm-0.12.tar.gz -C /opt

第三部 查看INSTALL

[root@xuegod1 safe-rm-0.12]# tac INSTALL 
all users on your system use safe-rm instead of the real rm.
Then, putting safe-rm in /usr/local/bin and renaming it to "rm" will ensure that

PATH=/usr/local/bin:/usr/bin:/bin

For example, if your path contains:

your path.
the usual "rm" command, make sure that you copy it in a location at the front of

In order to install safe-rm and make sure that it is being picked up instead of

第四部 安装配置

[root@xuegod1 safe-rm-0.12]# cp safe-rm /usr/local/bin/rm

[root@xuegod1 safe-rm-0.12]# ll !$

ll /usr/local/bin/rm

-rwxr-xr-x 1 root root 6179 3月   3 21:38 /usr/local/bin/rm

[root@xuegod1 bin]# export PATH=/usr/local/bin:/bin:/usr/bin:$PATH >>/etc/profile

[root@xuegod1 bin]# source /etc/profile

第五步 配置保护配置文件

[root@xuegod1 safe-rm-0.12]# echo "***">/etc/safe-rm.conf “ *** ” #需要保护的目录

#如果你操作 “rm -rf” 命令，如果目标在/etc/safe.conf文件中，自动提示safe-rm: skipping ***

当然，写个shell脚本去定时情况一个垃圾文件也是个不错的选择配合定时任务，就完美了。

愿每个热爱linux的同志们，加油！！！
