ok, so i have been messing around with the file system api. but cant seem to do this. basically i want to code my own lock but the password is stored in another file.

so you enter in the password and it goes to another file and checks.
can anyone help me out ?/>
thanks -Cheeky

fileName = "file"
password = "password!@#$%"

-- readfile
fileRead = fs.open(fileName, "r")
line = fileRead.readLine() -- reads the line
lineAll = fileRead.readAll() -- reads all the text in the line
fileRead.close() -- you must close the file!

-- writing
writeFile = fs.open(fileName, "w") -- 'w' for 'write', use 'a' for 'append' { Write = will overwrite what is in the text ; Append = will add to the file }
writeFile.write(password)
writeFile.close()

See if you can get it right with that />

Here are a couple of different ways to read file contents

local file = fs.open("fileName", "r")
contents = file.read() --should read the whole file

--or read it line by line
sLine = file.readLine()

It would be file.readAll() to read the entire file, if you insist on using fs.open.

Ya sorry about that, I usually use IO which you just need to do read().

[Lyqyd]

Ah, is the default for :read() to read the whole file? I know you can specify the mode thus:

handle:read("*a") --reads entire file in handle
handle:read("*l") --reads next line in handle

io.open() also gives you the very handy lines iterator:

for line in handle:lines() do
  print(line)
end
