split the filename on _ so you get the middle part and the first part. use module like File::Path or Perl's internal mkdir to create directories.
use File::Path;
  @l = split /_/,$_;  
  mkpath(...); # see the doc of File::Path for usage
  # or mkdir()

Hey ghostDog,

Thanks for the reply.. I have now got to a stage where i have the folder abcd in place but i need to create abcd/011112008/*.dat i used opendir to go inside "abcd" folder and again call makedir function i have written but i think I need to set the o/p put path unlike windows where you open the dir and do create dir :-) ..

Again thanks for your help ..any further inputs on this will be very helpful...

i dont' really understand what you want to do. if you want to create multiple directory levels, mkpath should be ok. read the docs for File::Path and see examples of how to use mkpath.

Hi ghostDog,

My question was i am unable to create multiple directories :-(
below is my code mkpath does not help much either..I have tried few things like "\" and "//" and "\ /" nothing seem to work ...

sub makeDir 
    my $new_dir = shift;
    if (!(-e "$new_dir"))
        mkpath([$new_dir “/” $Date], 1, 0777);
        #mkdir ($new_dir $rncDate,777);
        print "( $new_dir ) Directory has been created.\n";
}# end sub makedir

reply when you find time

the problem is your concatenation. how do you concatenate strings in Perl? check the docs.
