How to get the pastebin "nfsfd89" part?

I've been working on an antivirus, and I want users to be able to send the virus to me, via pastebin, but, I do not know how to get the "spaD8K9" part

It would work like this:

– Computer Uploads Code To Pastebin –
– Sends me the Pastebin Identifier via Rednet – This, how would I do this, how do I get the Identifier? e.x (6Si9H02)
– My automatic system downloads it as "Virus0024" –
– I get the virus to add to my Anti-virus –

Help please, it outputs true instead of what I want it too.
Code: pastebin.com/HZpgSwe6

Take a look into the pastebin program ;)/> Theres an output of the identifier, which you need to extract. I would copy the upload section of the program to my own and remove the output to the terminal, and send the identifier via rednet instead. The receiving computer just needs to call pastebin get id Virus0024 and there you have it.

As to your example or usage of that, I don't think anti-virus software makes a lot of sense in computercraft. It's really hard to do, and I can't think of a scenario, where you rely on something like this, as even real anti virus software is hardly any better than the normal OS security. I don't want you to stop your project, it's still cool to have done something like this, but just be aware of that.

Um, can I have an example, it keeps outputting true, instead of what I want.

From the Pastebin program that comes with CC:

local sCommand = tArgs[1]
if sCommand == "put" then
    -- Upload a file to pastebin.com
    -- Determine file to upload
    local sFile = tArgs[2]
    local sPath = shell.resolve( sFile )
    if not fs.exists( sPath ) or fs.isDir( sPath ) then
        print( "No such file" )
        return
    end

    -- Read in the file
    local sName = fs.getName( sPath )
    local file = fs.open( sPath, "r" )
    local sText = file.readAll()
    file.close()

    -- POST the contents to pastebin
    write( "Connecting to pastebin.com... " )
    local key = "0ec2eb25b6166c0c27a394ae118ad829"
    local response = http.post(
        "http://pastebin.com/api/api_post.php", 
        "api_option=paste&"..
        "api_dev_key="..key.."&"..
        "api_paste_format=lua&"..
        "api_paste_name="..textutils.urlEncode(sName).."&"..
        "api_paste_code="..textutils.urlEncode(sText)
    )

    if response then
        print( "Success." )

        local sResponse = response.readAll()
        response.close()

        local sCode = string.match( sResponse, "[^/]+$" )
        print( "Uploaded as "..sResponse )
        print( "Run \"pastebin get "..sCode.."\" to download anywhere" )

    else
        print( "Failed." )
    end

elseif sCommand == "get" then

Also, the pastebin you posted has been removed on PB

Someone tell me how to do this, I'm really confused.

Let's break it down, shall we?

if sCommand == "put" then
    -- Upload a file to pastebin.com
    -- Determine file to upload
    local sFile = tArgs[2]
    local sPath = shell.resolve( sFile )
    if not fs.exists( sPath ) or fs.isDir( sPath ) then
        print( "No such file" )
        return
    end

Bla bla bla, determining where the file is

    -- Read in the file
    local sName = fs.getName( sPath )
    local file = fs.open( sPath, "r" )
    local sText = file.readAll()
    file.close()

Reading the contents of the file

    -- POST the contents to pastebin
    write( "Connecting to pastebin.com... " )
    local key = "0ec2eb25b6166c0c27a394ae118ad829"
    local response = http.post(
        "http://pastebin.com/api/api_post.php", 
        "api_option=paste&"..
        "api_dev_key="..key.."&"..
        "api_paste_format=lua&"..
        "api_paste_name="..textutils.urlEncode(sName).."&"..
        "api_paste_code="..textutils.urlEncode(sText)
    )

POSTing the contents to pastebin's API, store the result

    if response then
        print( "Success." )

        local sResponse = response.readAll()
        response.close()

        local sCode = string.match( sResponse, "[^/]+$" )
        print( "Uploaded as "..sResponse )
        print( "Run \"pastebin get "..sCode.."\" to download anywhere" )

if we got a response, read the string returned and match all characters from the end of the string that are not a slash (/) The string will look something like this: "http://www.pastebin.com/eaf465", from which string.match gets "eaf465".

    else
        print( "Failed." )
    end

If we didn't get a response, the file wasn't uploaded!

I get that, I already tried that.
I used "return sCode", and I only got true or false when I did

a = shell.run("Uploader put Uploader")
print(a)

That's because shell.run only ever returns true or false. Why are you using a shell.run call there instead of the code you've been getting help with above?

Judging from the replies, this might as well be an xy situation. shell.run returns if it was successful or not, programs can't define their result. just try everyone else's code, they should work fine

Just for completeness, you could also do it the "hacky" way:

local oldPrint = print
local oldWrite = write
local line = ""
write = function() end
print = function(text) line = text end

local filename = "path/to/file"
shell.run("pastebin","put",filename)

local code = string.match(line,"Run \"pastebin get (.+)\" to download anywhere")

print = oldPrint 
write = oldWrite

print(code)
