wait.
this task won't take you longer than some ms (case #1) or seconds (case #2).
#1: you just sed / awk etc it
#2: you open a reliable text editor (like vi / vim, maybe also notepad++ etc) and search and replace the beginnings of the lines with valid data
This is very easy and basic file manipulation every computer users should be able to do (with help of reliable tools like sed/awk/vim/notepad++ etc)... And anyway the files are considerable small (not even hundreds or thousands of mega bytes, MB).
