    Put what you want to exclude or include into a file (eg. file1) one per line... Put the output of the directory contents into file2...
    grep -i -v -f file1 file2
    similarly if you wish to "match" everthing in file1 leave off the -v
    grep -i -f file1 file2
    the -i ignores case so leave that off if you wish an exact match (case sensitive)
    grep -f file1 file2
    the first file after the -f is always the "from" file

    Hello There,

    I was able to use the grep in order to ignore the files with pattern

    sub GetINDirFiles { my ($path) = @_; opendir DIR, $path or die $!; my @files = readdir DIR; my @files = grep {!/\_ACK_/} readdir DIR; closedir DIR; return(@files); }
    now the problem i have is that there are around 5000 files and later when i compare these files agains another list of files, it takes too much time.

    So i was thinking is it possible to list files which are between current time to current time - 15 minute?

    Thank You. -KAKA-
