True but you should always explicitly close your files. This gives you
a chance to report any errors it had, have rather than silently
ignoring them.

Even more readable:
FILE: foreach my $file ( @files ) }

last FILE if (some_condition);

recently stat-ed filehandle" in "the solitary

If you wish to terminate execution of a foreach loop without iterating over all
of the elements (@files, in this case) use the “last” statement:
foreach my $file ( @files ) {
# process file
open( my $fh, ‘<‘, $file ) or die(…);
while( my $line = <$fh> ) {
# process line
}
close ($fh) or d
That code will read each line from each file. The problem is likely in the
part that says:
#[process the lines & hash construction.]
What are you doing there?
