I'm creating a script to backup some files under dos in a tarball.... I
want to be able to save the last five backups.... I'm saving them in
dos_backup_060198_073456_1.tar.gz format.... How can I strip the tar.gz
and increment the 1 to 2....
For instance, I have dos_backup_060198_073456_1.tar.gz and
dos_backup_060298_073456_2.tar.gz and just created a new backup file,
but need to rename the previous two by incrementing the last number by
one, so the old dos_backup_060198_073456_1.tar.gz becomes
dos_backup_060198_073456_2.tar.gz, the old
dos_backup_060298_073456_3.tar.gz becomes
dos_backup_060298_073456_3.tar.gz and the new one is
dos_backup_060398_073456_1.tar.gz....
Here's the script so far....

#! /bin/sh
date=$(date "+%m%d%y_%H%M%S")
echo "Backing-up Windows95 files..."

echo "Checking for old backups..."
if [ -f /usr/local/backup/dos_backup_*_5.tar.gz ]; then
        echo "Deleting old backup..."
        rm /usr/local/backup/dos_backup_*_5.tar.gz
fi

for i in /usr/local/backup/dos_backup_*.tar.gz; do
        ******THIS IS WHERE I WANT TO RENAME THE OLD FILES*********
done

echo "Creating new backup file"
tar czf /usr/local/backup/dos_backup_${date}_1.tar.gz
/usr/msdos/windows/applic~1
