Re^5: find common data in multiple files

[afoken]

I tried this code using it as follow:

$ perl test.pl *.txt

And it is giving output:

$VAR1 = [];

Are you running the script in the directory containing the *.txt files?

What operating system are you using? If you are on Windows, there are some minor differences to Unix that prevent *.txt from being expanded to a list of files. In that case, add the following line to the perl script, right after "use warnings;":

use Win32::Autoglob;

(See Re^3: Perl Rename for details why this is needed.)
