Using Seq As A Variable With Padded Digits
Hi all. Im trying to use a sequence in a while loop like this below. I need it for navigating a year, month, day folder structure where a user can input the start date and have it go to the desired end date. The script will grab a certain file on each day then move onto the next. Ive got all that worked out using a static set of years in a for loop rather then a while loop with a seq. The problem is when I run into the month andn day folders as they are 01 02 03..10 11. Using the + 1 method it wont cd to the folders below 10 because the var is 1 2 3 instead of 01 02 03. Is there a way to make it add the zero to values below 10 but still keep count?



Code:
startdate=1
enddate=12
a=$startdate
if [ $a -lt 10 ]
   then a=0$a
   fi
 
while [ $a -lt $enddate ]
   DO OTHER THINGS HERE
   startdate=`expr $startdate + 1`
   a=$startdate
if [ $a -lt 10 ]
   then a=0$a
   fi
   done
