Technically, there's no difference between for and foreach
other than some style issues.
One is an alias of another. You can do things like this
foreach (my $i = 0; $i < 3; ++$i)
{ # normally this is foreach print $i, "n";}
for my $i (0 .. 2)
{ # normally this is for print $i, "n";}
- exec runs the given process, switches to its name and
never returns while system forks off the given process,
waits for it to complete and then returns.
