This is my logic.

file.txt content:
This is a test file.


Command:

output -o file.txt

then it shows the content of the file.. like this:

Title of the File: file.txt
Content:

This is a test file.

Open the file in read mode with the fs API, then just print(file.readAll())

Where should I put the file.readAll() ?

function printUsage()
   print("Usage: file [(OPTION)] [(File Name)]")
   print(" ")
   print("-find	-- Is an option that finds a file.")
   print(" ")
   print("-o	 -- It shows the output of your file content.")
end

local tArgs = { ... }
if #tArgs < 1 then
   printUsage()
end
local sCommand = tArgs[1]
if sCommand == "-find" then
local sPath = shell.resolve( tArgs[2] )
local tFiles = fs.find( sPath )
if #tFiles > 0 then
   for n,sFile in ipairs( tFiles ) do
	   if fs.exists( sFile ) then
		  print("File Exists!");
		  else
			 printUsage();
	   end
   end
else
	printError( "File does not exist!" )
end
end
if sCommand == "-o" then
  local sPath = shell.resolve( tArgs[2] )
  local tFiles = fs.find( sPath )
  for n,sFile in ipairs( tFiles ) do
	if fs.exists( sFile ) then
	  print("Title of file: "..sFile)
	  print("Content:")
	  print(file.readAll())
	else
	  printError( "File does not exist!" )
	end
  end
end

Right where you did, but you have to open the file first obviously. I assume you've used fs.open before?

Just answer next time. You clearly haven't used it.
http://computercraft.info/wiki/Fs.open
the mode you need is read ("r")

local file = fs.open(fileName,mode)
print(file.readAll())
file.close()

Thank you it works !!
