Hey Folks,

I Frequently use perl to process 2 files line by line.

Most of the times I compare two files line by line and check if one line is same to corresponding line of other file, or if one line is substring of other line etc and many more operations.

The technique which I generally use is to first save lines of two files in 2 different arrays.

Then execute a for loop where I compare corresponding index elements of the 2 arrays.

I guess this is not an optimize solution since if both files are huge creating large sized arrays may consume lot of memory.

So wanted to know if there is any better approach to process 2 files line by line.

Cheers,

Parag
