printf issue on Cygwin
Hi all,

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 Smilie

Now this is really weird. When i run now i get "invalid conversion specification" on both 10 and A

it's really annoying

Why do you expect it to work? In one instance you are setting the data variable to a string containing one character "A". In the other instance you are setting data to an integer i.e. 10.

In addition the printf format string provided by you (%02s) is invalid for ksh or /bin/printf.

From the printf(1) man page
Quote:
0

The value should be zero padded. For d, i, o, u, x, X, a, A, e, E, f, F, g, and G conversions, the converted value is padded on the left with zeros rather than blanks. If the 0 and - flags both appear, the 0 flag is ignored. If a precision is given with a numeric conversion (d, i, o, u, x, and X), the 0 flag is ignored. For other conversions, the behavior is undefined.

For the eleventeenth time, use printf "%02x" 0x$data (or %02X if you really need caps).

Thanks for your patience. I appreciate it.
