This is a follow-up to my recent post on how to store the nth line of a text file in a variable. The solution given won’t work for extremely long lines because the line requested by the user is stored in a variable and variables in Batch can only hold up to 8191 characters.
If you need to select an extremely long line from a file and save it to a new file, there is a workaround. But it ain’t pretty, or efficient. It involves
findstr, and a whole lot of temporary files. 😈
