Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:

There are files stored like 14.Aug.2014.log, 15.Aug.2014.log etc. in a folder $HOME/log you need to find out all the log files of last 1 month and move them into $HOME/logs/lastmonth/

this should be implemented with reference of file name.

The solution need be in efficient way.

2. Relevant commands, code, scripts, algorithms:
Commands : Awk, Date.
[Algorithm]

Find the 30 days back date
Get all the Log files in a variable called file_data
Awk the Date information from the File name (string)
Convert the File date from string to Numeric
Compare the each file date with 30 days back date
If the File date is older than 30days date move to Last month directory

[/Algorithm]

Code:

#!/bin/bash
date_30_days=`date --date="30 days ago" +"%Y%m%d"`
#echo $date_30_days
for file_date in *.log ;
do
        echo $file_date
        file_date_format=`echo $file_date|awk -F '.' '{ print $1 " " $2" "$3}'`
        file_date_numeric=`date -d "$file_date_format" +%Y%m%d`
        #echo $file_date_numeric
        if [ $date_30_days -ge $file_date_numeric ]; then
                mv $file_date ./lastmonth/$file_date
        else
                echo "NO OLD FILES"
        fi
done

3. The attempts at a solution (include all code and scripts):

Code:

#!/bin/bash
date_30_days=`date --date="30 days ago" +"%Y%m%d"`
#echo $date_30_days
for file_date in *.log ;
do
        echo $file_date
        file_date_format=`echo $file_date|awk -F '.' '{ print $1 " " $2" "$3}'`
        file_date_numeric=`date -d "$file_date_format" +%Y%m%d`
        #echo $file_date_numeric
        if [ $date_30_days -ge $file_date_numeric ]; then
                mv $file_date ./lastmonth/$file_date 
        else
                echo "NO OLD FILES"
        fi
done
