Shell Programming and Scripting

My note to you is not to post code without explaining the purpose and what you are trying to do. Others made the same comment; and also the moderators made notes to the same effect.

If you have some "great imaginative idea" or point to make, you need to explain your point and not just post some code fragment without explanation as if playing a game. Your comment:

... provides no explanation of what you are hoping to accomplish.

Sorry,Neo, just delete this post, it's my fault!

POSIX:

Code:

set 0 1 2
for i; do
  for j; do
    for k; do
      printf "%s " "$i$j$k"
    done
    printf "\n"
  done
done

I much prefer Scrutinizer's version because it doesn't use bash extensions. It easy to follow, and does not contain the dreaded eval command. The version in post #1 is one of the worst and most obscure pieces of code I have ever seen.

Might be an accident but the script appears to generate a sequence 0-222 working in number base 3.
