Can you please explain the command..
$4=sprintf("%d%s%s",arr[3]+2000,arr[2],arr[1])
thanks in advance
sprintf is a function to print formatted output. The % values in quotes represent the field arguments that follows & separated by commas-",". The %values indicate the field types i.e %d-decimal, %s-string. The fields have already been split into arrays and thus the new field $4 is given the new format and the acquired types. Hence from 02/03/09 (arr[1]/arr[2]/arr[3])which is our field 4 in the input is rearranged into arrays and formatted to print them in the required order. Our arr[3] should acquire the prefix 20, so we add 2000 to the value 09, and that's why it is a decimal value-for operation "+" purposes.
Regards,
Pawee
