How to Delete File Contents

[newzguy]

How do I delete a file's content? I don't want it to
append, I want the contents overwritten, how do I
do it? What I have is:

# Append the fetched data to the local file.

open out, ">>$localfile";
print out $result->content;
close out;

Does the >> have something to do with appending?


thanks

open my $out, '>', $localfile or die "Cannot open $localfile: $!";

print out $result->content;
close out;

Instead use

open out, ">$localfile";

See the documentation for open for more information.

How do I delete a file's content?

Many different ways.
- you could delete the file and then recreate it; however coming to think of
it this would create new file although with the same file name.
- you could open the file for writing and immediately close it again
- ...

I don't want it to
append, I want the contents overwritten, how do I

You don't want to append but you append?
Mind to explain?

open out, ">>$localfile";

Ok, you code comforms with the comment, but both of those conflict with your
spec.

print out $result->content;
close out;

What happened when you read the documentation for the open() function?
