root权限下:

cp rm.sh /usr/bin

chmod u+x /usr/bin/rm.sh

chmod 777 /usr/bin/rm.sh

 

$HOME/.bashrc中加入下面一句

alias rm=/usr/bin/rm.sh

效果如下:

rm rm.sh

(python2.7) appleyuchi@ubuntu:~/.Trash$ ls
rm.sh_16_13_38

来说下ubuntu18.10的

第一步：

#安装trash-cli工具，其实就是回收站的命令行模式：             

$ sudo apt-get install trash-cli

 

第二步：
#给trash命令添加别名”rm”，覆盖系统rm命令            

$ vi ~/.bashrc

#在最后一行加入：

alias rm="trash"

 #保存并退出            

$ source ~/.profile

 

以后不必删文件夹时加参数 -r 直接使用 rm file or  rm filedirectory

删除文件或文件夹，且删除后，它就会自动跑去回收站了！

每天一小步，人生一大步！Good luck~
