Sick Unix Trick #347 ... ghost files.

# Open the file, creating it open $fh, '+>', 'foo.txt'; # Immediately unlink the file ... it will remain # until you close the filehandle, then disappear unlink 'foo.txt'; # Put something in it to test print $fh "Foo\n"; # Rewind to the start of the temp file seek $fh, 0, 0; # Read it back in and see what you have $in = <$fh>; print "Read: $in\n"; # You don't even *have* to remember to close it, # but it is a good habit ... close $fh;

Updated: Note that unlike File::Temp, this trick will clean up after itself no matter what happens to the process. It does not depend upon DESTROY being invoked.
