in thread How does $. work in one liner?

In your example, you don't need the $_. This will print lines 1 and 2 from the file test.txt:

Assuming an OS that follows the POSIX spirit, this will also print the first two lines of a file, but probably without reading the entire file, and probably without starting an interpreter:

head -n 2 test.txt

(POSIX: head)
