Something like this
Put /path/to/Live* in a bash array
Then 'extract' the digit from the last member of array
Move Live to 'Last'.tmp
Then for each element of array, move to digit-1 (if 1, no digit)
Finally moving the Live(x).tmp to Live(x)
you may notice that bash arrays start at 0, (Live) , element 22 (Live22)
${#array[@]} will give you total number of elements 23 means last number is 22
