my $atime = (stat("filename"))[8];
The outer parens force list context, which you can then take the 9th
element of. (atime)
You can also do -
my @times = (stat("filename"))[8 .. 10];
And, just for fun:
my $times = { }; # empty hashref
@{$times}{qw/atime mtime ctime/} = # a slice of the hashref...
(stat("filename"))[8 .. 10]; # to which we map some of the fields of stat()
print $times->{mtime}; # should yield the same as (stat("filename"))[9]
Don't worry if the last snippet of code doesn't make any sense to you
- it doesn't make any sense to me either. :-)
