I'm thinking about just changing all special characters by adding a "\" before them, and then undo that change when the processing is done. Is that optimal?

Hey,

2 files, first one has 3 fields seperated by ||| and 2nd one is plain text.

I want to copy the lines from the first file if the 2nd field is present anywhere in the text file. This is what I've...
