The following code reads a file line by line: `my $filename = 'some/filename.txt'; open my $fh, '<', $filename or die "Couldn't read '$filename': $!"; while (<$fh>) { ... }` [download] If you want to store information about a file, do so while reading it line by line.	[reply] [d/l]

I need to open and compare multiple files and not open just one file. So I have to open files sequentially and compare. I am unable to get that through.	[reply]

Maybe you can repeat the code to open one time a second time and give it a different filename this time? Maybe now is a good time to revisit some introductory material on Perl. Maybe Modern Perl helps you. It is even available at no cost as a PDF download.	[reply]

I am sorry for posting again and again but as suggested by Laurent_R, load one file in memory and read all other files sequentially. I am unable to get through that as how to load one file in memory and open rest of the file sequentially for comparison.	[reply]
