rmtrash 是linux和mac下命令行版本rm的回收站，安装后对用户透明，符合正常使用rm的习惯(支持rm -fr file哦)，有了他再也不怕rm时候手颤抖了(能自动拒绝 rm -fr / 哦)。
rmtrash stands for "rm trash" which acts just like the system built-in rm command,and just moves the file to the trash for recovery when needed.

1、使用说明
（1）安装
wget --no-check-certificate https://raw.githubusercontent.com/LaiJingli/rmtrash/master/rmtrash.sh
mv rmtrash.sh /bin/
chmod +x /bin/rmtrash.sh

a、如果仅对单个用户启用回收站，只需第一次执行如下命令即可：
/bin/rmtrash.sh

b、如果想对全局所有用户启用回收站，需要修改bashrc全局配置文件后即可：
echo "alias rm=/bin/rmtrash.sh" >>/etc/bashrc

（2）使用
rm -h
Usage1: rmtrash.sh file1 [file2] [dir3] [....] delete the files or dirs,and mv them to the rmtrash recycle bin
Usage2: rm file1 [file2] [dir3] [....] delete the files or dirs,and mv them to the rmtrash recycle bin
rm is alias to rmtrash.sh.
options:
-f mv one or more files to the rmtrash recycle bin
-r mv one or more files to the rmtrash recycle bin
-fr mv one or more files to the rmtrash recycle bin
-rf mv one or more files to the rmtrash recycle bin
-R Restore selected files to the originalpath from rmtrash recycle bin
-l list the contens of rmtrash recycle bin
-i show detailed log of the deleted file history
-d delete one or more files by user's input file name from the trash
-e empty the rmtrash recycle bin
-h display this help menu

如果有问题，执行以下2条命令排查,或者退出重新登录系统
source ~/.bashrc
alias |grep rm

（3）如果需要彻底删除文件
a、# rm -e 清空回收站
b、# /bin/rm file 直接删除文件而不经过回收站

2、适用系统linux、mac osx
