Linux、mac的命令行下没有回收站功能,很多时候手一抖就把重要文件给 rm -fr * 了,虽然linux下有可能通过lost +found/debugfs找回,但难度也比较大,不能保证一定能够找回。人总是会犯错,本人工作这几年也犯过3次rm -fr删除后后悔的错误,与其后悔不如防范于未然,像桌面操作系统(windows、mac os、Ubuntu)一样加个回收站机制就可以了,经过几天的努力终于实现了,放到github上了,欢迎使用。

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,有了他再也不怕rm时候手颤抖了。
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.
提醒:rmtrash主要用于防止人为误删除操作,回收站本身不能替代系统正常的数据备份操作,数据备份依然非常重要。
