Change:

Code:

  system("/bin/find $ar[0] -mtime $ar[1] -type f -print >> /tmp/text.txt");
  system("/bin/find $ar[0] -mtime $ar[1] -type f -exec rm -f  \{\} \\\; >> /tmp/text.txt");

to:

Code:

  system("/bin/find $ar[0] ! -name '*.ext' -mtime $ar[1] -type f -print >> /tmp/text.txt");
  system("/bin/find $ar[0] ! -name '*.ext' -mtime $ar[1] -type f -exec rm -f  \{\} \\\; >> /tmp/text.txt");

where ext is the filename extension that appears on files you want to exclude from the list of files to be removed.
