local tArgs = { ... }
for k, v in pairs( tArgs ) do
   print( v )
end

I get userinput and want to seperate it, so I can run a program with the args the user has typed.

Because
shell.run(read()) not works and I dont want to have multiple reads for one program.

local function split(strI,regEX)
str = string.gsub(strI, regEX, " ")
str = str .. " "
local last = 1
local strTable = {}
for i=1, str:len() do
  if str:sub(i,i) == " " then
   local subStr = str:sub(last, i - 1)
   table.insert(strTable, subStr)
   last = i + 1
  end
end
return strTable
end

shell.run(unpack(split(read()," ")))

There is nothing…

If anyone don't understand what I mean.
Look at CraftOS. You can enter programs with args, how?

This is how the ComputerCraft devs do it in the shell program.

local function runLine( _sLine )
  local tWords = {}
  for match in string.gmatch( _sLine, "[^ \t]+" ) do
	table.insert( tWords, match )
  end
  local sCommand = tWords[1]
  if sCommand then
	return run( sCommand, unpack( tWords, 2 ) )
  end
  return false
end

This is how i'd do it, much more efficient split function

local function split( str, patt )
  local t = {}
  for s in str:gmatch("[^"..patt.."]+") do
	t[#t+1] = s
  end
  return t
end

I really dont get what you are asking, but if want to catch arguments when you run the program:

local tArgs = { ... }
for k, v in pairs( tArgs ) do
   print( v )
end

Maybe ipairs()? Order of table elements is undefined when using pairs(). But ipairs() gets tArgs[1], then [2] and so on integer indexes until it gets nil value.

local t = {1,7,5,7,4,3,7,9}
for k,v in pairs(t) do
  print('Index: '..k..' Value: '..v)
end
