Hello, perl programmers. 
foreach my $d(readdir(PROC)){
        next if $d !~ /^[0-9]+$/;

        my $procdir = "/proc/$d";
        open(IN, "<$procdir/status") || die "can't open status with$pr
+ocdir";
        while(<IN>){
            @a = split(/\s+/, $_) if /Uid/;
            $temp[0] = $a[1];
            @b = split(/\s+/, $_) if /VmSize/;
            $temp[1] = $b[1];

what is the fastest way to store a file into an array or a variable? because in my code, I open a directory and find a file that I want to open, and store the name of the file into the variable $d, but by the time when I try to open that file, that file is already gone. so i get an error message saying it can't open the file. Is there anyway to prevent this? like as soon as it sees the file name, open it and store it in a variable to prevent the error? Thanks.
