I can't use PHP commands to do this. I can only have an ereg statement, but that has to be placed in a grep statement. Maybe I should ask a Unix list, but I figure with the ereg(i) expertise here, this is my best bet. By the time my shell_exec() call returns its results, it should return only those files with the actual number. At that point, I can't explode() it and start searching for the number all over again using in_array() or any other commands. By the time Unix returns its results, the only thing I can do is carry on assuming I have only those tags that contain the number without having to search through the array. I appreciate the help, but while these commands would work in some situations, it won't work in mine. The whole finding-if-it's-in-the-list thing has to happen in the ereg that I pass to grep. __________________________________________________ Do you Yahoo!? Yahoo!
