lock a folder? question

Hello.


i have 1 question:


is it possible to make a lock to a folder so:

> ls main

then when i hit the enter, it asks for a password????
do i need a program for that? or do i need to edit the Bios setup?


thanks in advance

well you have edit BIOS functions but to do so but you do not necessarily have to edit the BIOS file to do so, you can edit functions in programs (like your startup file)

the function you need to edit is the fs.list function, just alter it so it uses the original fs.list to get a full list, uses your code to modify the list and remove any hidden folders and then return the list

Thanks for that, but can you give a quick example on how to hide em? I dont know if there exists fs.removeList()

but thanks. I think then:
shell.setAlias("test")
input = read()
If input == "ls" then
fs.removeList(hList)
Shell.run("ls")
end

i know there Are some big start letters, but im typin on my phone.

is that right? Or am i fully wrong in my code?

here we go

if not fs.hide then
  local ls=fs.list
  local tHidden={}
  fs.list=function(...)
   local results=ls(...)
   for k,v in pairs(results) do
    if tHidden[shell.resolve(v)]==true then
	 table.remove(results,k)
    end
   end
   return results
  end
  rawset(fs,'hide',function(dir)
   if fs.exists(dir) then
    tHidden[shell.resolve(dir)]=true
    return true
   else
    return false
   end
  end)
end

after executing that code use fs.hide(filename) to hide something and fs.list will not find it

i did this:
EDIT: Never mind… i figured it out… i just had to set "for k,v in pairs(results) do" to "for k,v in ipairs(results) do"
THANKS!

if not fs.hide then
  local ls=fs.list
  local tHidden={}
  fs.list=function(...)
   local results=ls(...)
   for k,v in pairs(results) do
	if tHidden[shell.resolve(v)]==true then
		 table.remove(results,k)
	end
   end
   return results
  end
  rawset(fs, 'hide', function(dir)
   if fs.exists(dir) then
	tHidden[shell.resolve(dir)]=true
	return true
   else
	return false
   end
  end)
end

fs.hide("rom")

Edit2:

But… can i, with this, also make a password lock for the "Rom" folder… so when you type "cd rom" or "list rom" or "ls rom" then it will aske for this:


######################################
#THIS FOLDER IS PASSWORD PROTECTED!#
######################################

############
Enter Password
>
############

is that possible?
thanks :D/>

well at least it works :)/> enjoy

you should build an entire attrib library for hidden, system, read only etc

oh EDIT


i found a error? i want to hide 2 files… but when i then type in "test" (the program your example was in) then it shows the fs.hide("startup") which was the first, list i want to hide… what should i edit, for that?

but thanks..

current code

if not fs.hide then
  local ls=fs.list
  local tHidden={}
  fs.list=function(...)
   local results=ls(...)
   for k,v in ipairs(results) do
    if tHidden[shell.resolve(v)]==true then
         table.remove(results,k)
    end
   end
   return results
  end
  rawset(fs, 'hide', function(dir)
   if fs.exists(dir) then
    tHidden[shell.resolve(dir)]=true
    return true
   else
    return false
   end
  end)
end
fs.hide(
"rom"
)
fs.hide(
"startup"
)

you do not need to run my program twice to hide multiple files, it adds an interface you can use to hide whatever you want so start by running test, then use the lua prompt to hide startup fs.hide('startup'), then do the same for rom fs.hide('rom'), you do not need to run test again, that will hide both folders

Edit: now it works out…. thanks…

i will try to make that password thingy magic but i dont think i can….
because i dont know if i should edit the bios, or the "test"

but thanks anyway.

what do you mean password? if you need help feel free to ask

Okay.. As i think you saw in the head description ,i said that if i type in

"cd main" "ls main" "list main"

then it will ask like this:

#########
enter password, to go to this config.cfg:
#########

####
> [password]



but i think then, i need to edit bios. Am i right to that?

well it is pretty much the same as before, you need to edit bios functions which can be done in the test program
