How do I replace line breaks into a space?
for examble using string.gsub()?
e.g.:

into:
"str1 str2 str3"

I'm getting the string from a file and a few special lines i'm saving in a string..
The problem is that the strings has the line breaks form h.readLine() too
so I want to convert the line breaks to a space caracter

When you read the string from a file, using file.readLine, it deosn't append a new line at the end.
Post the code you use, so we can see what's wrong.

Mhh.. okay
Then textutils.serialize() might be the problem?
Anyway here is part of my code:
xread = h.readLine()
while xread ~= "version:" do
if xread == nil then
errorStop()
return
end
xstr = xstr.." "..xread
xread = h.readLine()
end
xprogramPack[2] = xstr
This works fine at the moment!
Because I'm using a table in a table (what in lua doesn't work) I need to covert my 2nd table in a string using textutils.serialize()
This string I'm copying in the main table…
If I using textutils.unserialize() I am getting the error: attempt to index ? (a nil value)
If I print the string without unserializing I see line breaks..
Where I've got my line breaks in my file I've got it in the table too.. :P/>/>

Nope! You'll get the error: index expected, got nil

Are you sure there's line breaks? Cause if you use print or write, it adds them automaticaly to fit the screen, try with term.write.
Also,
Because I'm using a table in a table (what in lua doesn't work)
What do you mean that they don't work? You can do something like:
local t = {}
t.sub_table = {}
t["sub_table"][1] = "some value"
print(t.sub_table[1])
