The program "pastebin" errors with:
pastebin:101: attempt to index ? (a nil value)

You probably overwritten the program yourself, because pastebin works for me and everyone else who don't have a modified pastebin

Can't really overwrite a program in rom/programs, as it is read-only. Unless he did it externally i guess. He could however have put a program named pastebin in the root folder.
Try running edit pastebin and see if there's anything in the file.

It could be a replacement in root, or an overridden function. But I think it's rather more likely that he just threw some parameters at it that it can't make sense of.
What exactly led up to that error? You've only told a fraction of the story, Flick.

Yea, taking a look at the pastebin file reveals this:
Which seems an unlikely error really, unless the path you're providing is full of weird characters maybe. You've probably got a custom rom or something. The programs are pretty well built to prevent errors.
-- GET the contents from pastebin
local res = get(sCode)
if res then
local file = fs.open( sPath, "w" )
file.write( res ) --this is line 101
file.close()
print( "Downloaded as "..sFile )
end

Judging by the code Oeed posted, this might be the result of trying to save a paste to a non-existant folder.

I just tried doing that, it throws a different error (line 92). But that's something that should be fxied.
For everyone's reference, here's the code of the vanilla pastebin (1.56).
Spoiler
1:
2: local function printUsage()
3: print( "Usages:" )
4: print( "pastebin put <filename>" )

It's even numbered :P/>
I keep a copy of the rom in a folder, it's very useful to reference. Especially if you don't have access to the wiki.

Moved to Ask a Pro. Try reproducing this on a computer with no startup file after a fresh boot.

I've already done it, but in the future click the 'Report' button in the bottom right of the post and type 'Please lock this'.
