Hex Conversion

I need to have my scripts import volume groups and mknod devices files. I have most of the script working but the device file needs to be in the format 0x??0000 (where the question marks are my HEX representations of the volume group number. I have the code below and the output it produces which would work great except anything that is only one charater will not work (I.E "1" needs to be "01", "a" needs to be "0a"). Any suggestions? And I can't use any perl code.

#!/bin/sh

for y in vg01 vg02 vg03 vg10 vg21 vg22 vg23
do
printf "%#x\n" $(echo ${y} | sed 's/^vg//') | sed 's/0x//'
done



Output:

1
2
3
a
15
16
17

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable an environment as possible, removing most environment variables and with the current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script. service passes COMMAND and OPTIONS to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start com- mand. service --status-all runs all init scripts, in alphabetical order, with the status command. EXIT CODES
service calls the init script and returns the status returned by it. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
/etc/init.d/skeleton, update-rc.d(8), init(8), invoke-rc.d(8). Jan 2006 service(8)
