I was wondering what is the best way to do "Zero Padding" in Bash. Suppose you need to iterate through a for loop and you need 01, 02, 03 sequence instead of 1, 2,3 then that is Zero padding.
Some of the methods I could get from the internet.
1. Using printf
for ((i=2;i<16;i++)); do printf "%02d" $i; done
2. Using seq
There were couple of solutions when you use seq
* seq -f '%02g' 1 15
* seq -w 1 15
Enjoy being fast using bash..
