Hello all,

I am building a shell script. Every morning my shell script will trigger an external system backup script and the backup file (File Name format: "20030929backup.bkp" (i.e)current date + "backup.bkp") will be stored in the backup directory. After successful back, I need to keep only 10 backup files in the backup folder at most. Say on 11th day, day 1 file should be deleted and the 11th day file should be created. What's the best way to do this?

I am using the below command to get the list of backup files from backup directory.
$ find /home/EBI -name "*.bkp" -exec ls {} \;

We need to calculate the calendar days.

I thought of using (-atime +10) but, the thing is this backup script will not run on Sundays. So we miss one day... I guess we may need to count the number of backup files, find the oldest one, delete it and add the current file. What's the simple way to do this?

Thanks.
