Add leading zeros to running number

Hi everyone,

I need to append leading zeros to a running number.

How should I do it?

I tried this but I keep getting errors.

if [ expr $counter <= 9 ]
     then
        counter1 = "0000"$counter
     else
        if [ expr $counter <= 99 ]
        then
           counter1 = "000"$counter
        else
           if [ expr $counter <= 999 ]
           then
              counter1 = "00"$counter
           else
              if [ expr $counter <= 9999 ]
              then
                 counter1 = "0"$counter
              fi
           fi
        fi
     fi


Is there another way like append "0000" to $counter, then reverse the string and cut the 1st 5 bytes, then reverse the string back again.
