CentOS Implementation Recycle Bin mechanism

As an operator, delete files on the server in order to facilitate the frequent use of the RM *.txt such wildcard characters, even for the sake of-rf parameters, if it is OK, if the deletion of an inattentive, it can be big.

As the saying goes often in the river standing where there are not wet shoes, no one can guarantee that they can not make a mistake, but every day fear of the whole into an obsessive-compulsive disorder is not a thing, so think of the Linux server is also the whole of a similar to win's Recycle Bin function.

The following is a script I implement the Recycle Bin, if you need to delete files after the Recycle Bin is enabled, simply execute "del file name/folder names"

1 [[email protected] tools]# tree trash_1. 0/2 trash_1. 0/3├──install_trash.sh4 └──trash_mkdir.sh

Very simple, two script files, trash_mkdir.sh is written to the crontab scheduled tasks, responsible for generating the corresponding date of the Recycle Bin folder every day, and regularly clean the Recycle Bin more than 5 days of files, that is, the Recycle Bin can keep you deleted files within five days, Install_ The trash.sh script is responsible for automatically configuring timed tasks, loading user personalization configurations, and so on.

Deployment notes:

1. Put two scripts in the same directory

2, use the user who need to enable Recycle Bin function to execute install_trash.sh script can install with one click

The above is my Centos6.5 server on the implementation of the Recycle Bin mechanism, interested friends can discuss the improvement together.
