You said:

I'm trying to execute the unzipper from a command in a popular upload script.

And for some reason, that "unzipper" is named "no-frills.exe". Okay, fine. When I searched your code for "no-frills", I found this line (not quite half-way down, at line #464):

open my $wfh, "| no-frills.exe $uploadedfile";
[download]

Then I searched for "$wfh". Wouldn't you know... that variable name occurs only once in your 1K lines of code, at that very line #464. So, you open a pipeline file handle to write to this "unzipper" program, but you never write anything to the file handle -- at least, that's how it is in the posted code.

What would you expect to happen, given that the pipeline file handle receives no input?

BTW, while you're fixing that, you might also want to give the full path name to the program when opening the pipe -- there's no guarantee that the web server process knows where it is (has this program in its execution PATH).

• 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).
