for doesn't fork so the realy small commandline limit isn't a problem. But are you sure the shell does not read in a full list for "*" and then work through that?

Depending on the shell you get different behaviours. In this simple case it seems to work out right but take the following as an example: (my normal shell is zsh) [EMAIL PROTECTED]:/tmp/bar% touch "a b" [EMAIL PROTECTED]:/tmp/bar% L=`find` [EMAIL PROTECTED]:/tmp/bar% for i in $L; do echo $i; done
