One way in Bash could be:
n=$(printf "%-9s" 2457)
printf "%s\n" ${n// /0}

printf "%s%0*d\n" ${X} $((9-${#X})) 0
printf "%s%0$((9-${#X}))d\n" ${X}

The latter suggestion is portable.
Once defined as a function it becomes handy:
rightpad0() { printf "%s%0$((${1}-${#2}))d\n" "${2}"; }

rightpad0 9 2457
