6. 最重要的恢复 ( 2016-9-29) 

今天终于用上了.

昨天晚上误删了 好商城 (33hao ) , 所以今天开始恢复. 

$ trash-list 列出所有的项目

$ restore-trash :  会列出可以恢复的项目,然后输入数字,例如: 

$ restore-trash | grep hao
root@iZ25kkl41woZ:/opt/app# restore-trash | grep hao
1644 2016-09-28 17:10:54 /opt/app/33hao
1768 2016-07-17 21:20:41 /opt/app/33hao.zip
# 然后直接删掉就可以:

$ restore-trash 

... 列出好多

输入: 1644    回车, 发现东西就回来了.
