How do I search for a word pattern like "Var_x_longitude"
"Var_y_latitude" two files to see if such words are in these two files?

I was trying to open a file and do a (/\bVar*e\b) and then try to save it in an array. Then open the 2nd file and compare the array with the pattern. But I failed.

I found out here that there is a command like 

perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/' fileA fileB >output

[download]
but I dont' understand it and it only matches the length of the lines in two files.

I have a variable and want to see if they are used in these 2 files and want to see the display or the lines either on standard out or > output.txt. Can anyone help? I'm not good at programming. Using C seems even harder.

Any help would be appreciated much. Thanks.
