CGItemp files

Posted by TedH (TedH), 5 October 2005
In writing a Perl based CMS, I've run across a weird thing that happens when a file is uploaded. My script can add, edit and delete the text based files nice as you please. If an image is needed I can upload to the correct folder in the webspace fine.

However, on a Windows based machine a file named CGItemp***** (***** = random number) is created in the same folder as the upload script and left there. The CGItemp file is the same size as the image that was uploaded - so I understand why it's there.

Now on Apache/Unix (evidently), this gets deleted immediately - but not on a Windows server.

This seems to be a common problem and the replies I've seen say cgi.pm takes cares of - no it does not. Only by FTP'ing in and manually delete does it go.

I've got a feeling that there must be some way to unlink any file in that folder that begins with CGItemp, but don't know it.

Any suggestions?

cheers - Ted

Here's an example that deletes all files that match a particular pattern in a particular directory.   I've printed out the names and NOT deleted them in this test code - just uncomment the unlink line to make it work.

Code:
$dirname = "/Library/WebServer/cgi-bin";
opendir (DH,$dirname);
@getrid = map("$dirname/$_",grep(/\.tgz$/i,readdir DH));
# unlink @getrid;
print "@getrid\n";


To change to CGItemp files, replace the \.tgz$ regular expression with ^CGItemp.   I have used the "i" (ignore case) modifier because you're talking Windows in the question ....

Thanks Graham, that works very nicely.

Now I can have an option for Windows users so the temporary files can be purged.

Did you ever get the directory done that you mentioned?

cheers - Ted
