I don’t open big files at all. There’s no point. Files exist as data made to be transformed from one form to another. It is only worth looking at a file in its final form unless you are making some kind of edit.

And even then, I make edits on large files through a series of commands, never opening the file.

By thinking of files in this way, it becomes easy to create programmable tool chains for manipulation.

What's your typical strategy for parsing something like a large text file for some relevant data?

Suppose you could cat and grep, but what if you don't know what you're looking for?

not everybody uses a computer for the same exact thing you use a computer for

Of course, if they did there would be no point in making my comment, it would be redundant.

I think the issue with your original comment is with "there's no point," which is in effect invalidating the opinion of others.
