So here is my code

k = " ****************************************"
error = " Unable to start OS"
OS = "os"
function os.pullEvent()
local event, p1, p2, p3, p4, p5 = os.pullEventRaw()
if event == "terminate" then
term.setCursorPos(22,16)
print "NO HACK"
term.setCursorPos(18,4)
sleep(1.5)
shell.run("startup")
end
return event, p1, p2, p3, p4, p5
end
term.setCursorBlink( false )

print " Username does not exist"
sleep(2)
os.reboot()
–Username Incorect
end

And it is a login screen. but here is what it does. When i starts it needs a file called "Users" and then a user account name.
EX:
Username: test
then the file is test.txt and inside is the password.
It works with finding the username…
But not the password inside the file…
I tried lot's with this.
Help me out…

you can use the fs api, I think its better. Replace this piece of code in your program:


Call = io.open("Users/"..user, "r")
--Username Correct
--Display Password
term.setCursorPos(2,8)
write "Password: "
pass = read "*"
--Display Password
--Password Correct
if pass == Call:lines() then
term.setCursorPos(7,16)
print "...Loging In..."

through this:


Call = fs.open("Users/"..user, "r")
--Username Correct
--Display Password
term.setCursorPos(2,8)
write "Password: "
pass = read "*"
--Display Password
--Password Correct
if pass == Call.readLine() then
term.setCursorPos(7,16)
print "...Loging In..."

Just change:


if pass == Call:lines()

To:


if pass == Call:readAll()
