Re: Perl script does not work

While '>temp.txt' is quite safe, with "<$file", $file is interpolated.
That interpolation can have unintended effects.

My bad, I hadn't seen the OPs "<$file". I read it as: use

open my $fh, '<', $filename ...

I prefer:

open my $fh, $filename ...

Unless:

In the OP's case, there is no guarantee on what characters may appear in
the filename. In that particular case, perldoc -f open specifically
recommends the 3-argument form:

[...]

If the OP had limited the possible filenames to be processed by
filtering them in some way, I would not have made the recommendation.

Therefore, I find it better to stick with the three argument form unless
there is a specific reason to prefer the two argument form.

clear, thanks. Should have had a better peek at the OP's post, apologies.
