how do prlglobs expand (was Re: 'nobody' using sudo -- scary!)

This raises an intersting pint )for me at least)

I'm not that used to perl globs:


let's assume I work in a setup where /home/*/.forward expands to > 15000 files.


What would happen if I use follwing statement in perl"


foreach my $file (</home/*/.forward>){
do_something($file);
}

would perl
- iterate through the files
- or would perl first create a list of all the files and then
iterate through them.
- or would it hit a linit and not provide all hits.
- or does it depend on the system perl is running on
?

Just being curious?

Neither of which would necessarily work if /home were an automount point, as "*" won't expand (and if it did, could have > 15000 matches in at least one case I know of, which is why you wouldn't want it to expand).
