Monks!!!

Hi there, my question is about how I could open a file and delete its content, but not the file itself. The reason is that my program opens a large text log file and if this file is larger than 5MB my program zips it and delete whatever is above 5MB, but it is leaving behind some junk left over from the over size file. I decided that the best way is to get the size of this log file and if it is larger than 5MB just zip this file, store the zip file somewhere, than open the original log file and delete the contents of it. I am having a problem open this file just to delete its content.

Thanks for the Help!!

Here is just a sample of how open a file, but what about deleting its content?

#!/perl/bin/perl
    use strict;
    use warnings;

    open (FILE, '<', 'sample.txt') or die "Could not open sample.txt: 
+$!";
    while (<FILE>) {
        ....?????
    }
    close (FILE) or die "Could not close sample.txt: $!";
