Hello,

I'm attempting to study Brace Expansion at the same named page at bash-hackers.org and it states the following -
Generate numbers with a prefix 001 002 ...

Using a prefix:

for i in 0{1..9} 10; do printf "%d\n" "$i";done

However I am getting *this* output when running their command in Terminal In Ubuntu 8.04

address@hidden:~$ for i in 0{1..9} 10; do printf "%d\n" "$i";done
1
2
3
4
5
6
7
bash: printf: 08: invalid number
0
bash: printf: 09: invalid number
0
10

So... what gives??? I tried looking at info coreutils 'printf invocation', and it does not even explicitly spell out what the %d argument means, instead it just tells me "it's like the C printf, except for these differences". I have never used C, and have no idea where to look it up, so what good is that info page??? I'm trying to learn bash, and have no desire to learn to program in C.

Later, Ray Parrish
