this is the first time I'm posting a question, so I apologize if my etiquette isn't quite right...

I am performing a simple search-and-replace on a large file - a very large file - already in an array and writing out to a new file. Then, I have a few system() statements that manipulate files. The problem is, my program seems to be skipping my system() statements. My instinct tells me it is because of the file size, but I don't know how to fix it. My code looks like something like this:

open(OUT,">outfile") || die;
for($i=0;$i<=$#bigfile;$i++){
  $bigfile[$i] =~ s/\0/ /g;
  print OUT "$bigfile[$i]";
}
close(OUT);
print "Compressing original file\n";
system("compress original.file");

print "Concatenating other data\n";
system("cat ./incoming/data.file ./static/data.file >> outfile");

print "Sorting Data File\n";
system("asort outfile clean.data 1 6 8 9");

print "Done.\n";

The odd thing is that it performs the print statements correctly, but the system statements are all skipped. Any ideas? (part of the reason my instinct tells me that it is filesize is that it has worked fine for the entire year up until now - and that's the only variable I can think of that may affect this)

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• 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).
