file = io.open("/system/build.prop")
local number_of_loop = 0
local extracted = {}
repeat 
  text = file:read("l*")
  number_of_loop = number_of_loop + 1
  extracted[number_of_loop] = text
until number_of_loop == 7

gg.alert(extracted[7])

Simple loop to get seventh line in the file.

you're welcome, if the line is not stable but text has a changing pattern, you can use string.gmatch to find the text you want.
