Hi All,

I have written the follwing script to take the backup of the file every day
along with the date.

DATE=`date +%Y%m%d`

export DATE

cp var/hr/hr333m.txt cp var/hr/payments/hr333m_$DATE.txt

The file name as follows after taking the backup.

hr333m_20110630.txt

Could you please help me to remove the backup file,if it is 7 days old compared to the server date.

Thanks in advance.

-name "hr333m*" -- it will match only the files starts with hr333m

if you have any doubts, then just print the find command output, once you satisified with the output, apply the rm command.

To display the files :

find var/hr/payments/ -name "hr333m*" -mtime +7

To Delete the files : (Once you satisified with the above command)

find var/hr/payments/ -name "hr333m*" -mtime +7 -exec rm -f {} \;
