I think your solution is fine. If you want to get fancy, you could use my Tie::Handle::Argv, which is the basis of my File::Replace::Inplace, an emulation of the -i switch (note: Perl v5.16 strongly recommended):

use warnings; use 5.016; package Tie::Handle::FancyThingy { use parent 'Tie::Handle::Argv'; use File::Basename qw/fileparse/; sub OPEN { my ($self, $origfn) = @_; my ($fn, $dirs, $ext) = fileparse($origfn, qr/\.[^\.]+$/); my $outfn = $dirs.$fn.'.out'; print STDERR "Debug: $origfn => $outfn\n"; open ARGVOUT, '>', $outfn or die "$outfn: $!"; select ARGVOUT; return $self->SUPER::OPEN($origfn); } sub inner_close { my $self = shift; select STDOUT; return $self->SUPER::inner_close(@_); } } tie *ARGV, 'Tie::Handle::FancyThingy'; while (<>) { chomp; say translate($_); } sub translate { return "<".shift.">" }

A more simplistic approach might be to just use the -i switch to write the "backup" (input) files to a different directory and then rename the output afterwards.

Minor edit to code: Replaced my $ofh (output filehandle) with the more appropriate ARGVOUT.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
