Path::Tiny handles opening and closing and doing different things to a file. Its methods include spew(), but the module's own documentation recommends using append() for what you want since it locks the file and overwrites it, whereas spew() creates a temporary copy. 

[18:25][nick:~/monks]$ cat 1135741.pl 
#! perl -w
use strict;
use feature qw/ say /;

use Path::Tiny qw/ path /;

my $file = 'test.dat';
my @lines = path( $file )->lines( { chomp => 1 } );

# do something with @lines ...

my @append = (); # empty array
path( $file )->append( @append, { truncate => 1 } );

say "Done.";
