I know that they have the fs.open("string", "read or write")
but is there a way to make it read only a certain part of the file?

Why would you need this? Reading the entire file seems pretty good to me.

If you mean say extracting a particular line then you could do something like this
local function readLine( path, lineNum )
local handle = fs.open( path, "r" )
local line
for i = 1, lineNum do
line = handle.readLine()
end
handle.close()
return line
end
obviously this could be modified to ignore particular lines too. or you could modify it to read a subset of lines, but they would need to go into a table.

Although I would probably use two unique variable names instead of line twice :P/>

Yeh probs, wrote this when I just woke up and forgot that I did that :P/>
Scope means it should work, but for readability its better to name them differently.

Uh, no, the loop would throw an error. Amounts to for i = 1, nil do.
