Value too great for base (error token is “09”)

Question

When running this part of my bash script am getting an error

Script

value=0
for (( t=0; t <= 4; t++ ))
do
d1=${filedates[$t]}
d2=${filedates[$t+1]         


        

Answer 1

For 'mm' and 'dd' values in dates, I use this trick:

mm="1${date:5,2}"  # where 5 is the offset to mm in the date
let mm=$mm-100     # turn 108 into 8, and 109 into 9
