I am running a simple test on Cygwin and having this problem. Can someone provide me a fix or alternative?

#!/bin/ksh

data=10
printf "%02s" $data

data=A
printf "%02s" $data

The result should be 10 and 0A

But i am getting
printf: "%02s": invalid conversion specification
0A

So it seems like it is not working when data=10

Stuck again Smilie

%02s is not a valid print format specification for a string in ksh

fpmurphy,
Why is it working in bash and not ksh? Is there a alternative i can acheive in ksh instead?

i basically want to pad with leading 0

no hexadecimal here; straight up strings
data=10; output should be 10
data=A; output should be 0A
data=2; output should be 02

i tried in bash and its working. I need to get this going in ksh
Please help

Again, this issue with ksh is just only when i run on Cygwin - i have installed pdksh package.
