Differentiate && modify files by date Mtime

Simulation Scenario:

In a directory, there are a large number of files generated in different days, and the name of the file does not have a date identification, how to divide the files by date into different folders.

According to the date the file was modified, mtime the file.

> Date

Tue Dec 14:04:04 CST 2016

Modifying the mtime of a file

/sysout> touch-c-t 12180010 file{101..200}

12180010 = December 18 0:10

/sysout> Find-mtime +1-type F | More

./file135

./file168

。。。

Verify the number of files

/sysout> Find-mtime +1-type F | Wc-l

100

/sysout> L file102

-rw-r--r--1 testuser testuser 0 Dec 00:10 file102

Date the backup file was created

> Date--date= ' 2days ago ' +%y%m%d

20161218

Backup scripts

> VI baklog.sh

#!/bin/bash

Logdir=/sysout

Logdate= ' Date--date= ' 2 days ago ' +%y%m%d '

bakdir=/backup/$LOGDATE

CD $LOGDIR

mkdir $BAKDIR

Find-mtime +1-name "file*"-exec mv {} $BAKDIR \;
