single digit decimal to 2 digit hex

[OieL]

how can i convert a single digit decimal to hex value but with a 0 preceeding it ..

ie

printf "%X%X%X", 0,1,2 ;

will output 012

how can i make it ouput like "000102" im doing this to convert RGB color values to hex (html color chart).

Well, I suspect that your actual print statement looks different that the one you posted, but if you stuff your RGB values into an array you can format it using

@rgb = (0, 1, 2);
printf "0"x(6-@rgb)."%X"x@rgb, @rgb;

jaa

This works:

printf "%02x%02x%02x\n", 0,1,2;
