This is how progress bars work
```my @files = qw/ a b c d e f g/;
my \$total_steps = int @files;
my \$step = 0;
for my \$file ( @files ){
\$step ++;
print "\rStep \$step / \$total_steps\n";
select undef, undef, undef, 0.3;
}
print "Done\n";
__END__
Step 1 / 7
Step 2 / 7
Step 3 / 7
Step 4 / 7
Step 5 / 7
Step 6 / 7
Step 7 / 7
Done

Close, but it's a bit more like this:

```\$ cat t.pl
my @files = qw/ a b c d e f g /;
my \$total_steps = int @files;
my \$step = 0;
for my \$file ( @files ){
\$step ++;

my \$t = rand;
\$t *= 3 while \$step / \$total_steps - .01 > rand;
print "\$t\n";
sleep \$t;

print "\rStep \$step / \$total_steps\n";
select undef, undef, undef, 0.3;
}
print "Done\n";

\$ perl t.pl
