[Closed][Lua][Question] How to make, write in and read from a file

Hi guys i really need your help.

I tried finding a good explanation how I could just wirte a litte "1" or "100" or something in a file whit the fs.*** api, but i failed. So please can you help me with a litte example out, just creating, overwrite and read from a file whit a variable.

Thank you for reading and may supporting :)/>

local handle = fs.open(yourFile,mode) --"w" will write to the file and "r" will read from the file
handle.writeLine(yourTextHere) --Must be a string
handle.close() --You must always close the file you are manipulating

The wiki also has an excellent documentation of all the functions that the fs library reveals

Here is what it should look like:

local file = fs.open("test","w") --Using write will automatically wipe the file of its contents. Append("a") will not, it will insert the text at the end of a file
file.writeLine("1")
file.close()

Reading the file:

local file = fs.open("text","r") --Open the file in read mode
local data = file.readAll() OR file.readLine() depending on what you need. In this case it will be readLine
file.close()
print(data)
->1
