Hello Monks,

I am trying to read multiple files in my perl program. I am using UNIX "ls" command to do the task.

I need to know whether it is the best way to do this to read from following directory structure: 

/Data_Files/2010_07_07_15h32m/Data.txt
/Data_Files/2010_07_07_16h21m/Data.txt
/Data_Files/2010_07_07_16h24m/Data.txt
/Data_Files/2010_07_07_18h38m/Data.txt
/Data_Files/2010_07_07_19h11m/Data.txt

[download]
#!/usr/bin/perl 
#my @files = ('data1.txt', 'data2.txt', 'data3.txt' );
my @files = `ls Data_files/*/Data.txt`;

foreach my $filename(@files){
    open FILE, $filename or die "Cannot open $filename for reading: $!
+\n";   
    ### Read Line by Line ###
    
    while($line=<FILE>){
    #read file line by line
    }
close(FILE);
}

Thanks!!!
