autosys - How can I concatenate a file and string into a new file in UNIX as a one line command -

I need a very simple (hopefully) 1 liner command that reads a file that adds a string and gives output to a new file, without changing the original data

  file 1 string ------ ------ apple orange banana   
 magic comma  
  Faille File 2 ------ ------ Apple Apple Banana Oranges   
 Basically, cat file 1 + 'oranges' & gt; File 2  
 I am using  Autosys  to run the command, and I'm pretty sure this is  & amp; Amp; & Amp; Amp;  or ;  As part of the same command.   
 
 
 You can:  
  (cat file 1; Echo 'oranges') & gt; File2   
 which will create a subshell, which will beat file1 in stdout, then align with stdout. And we capture all those outputs and redirect it to a new file, file 2.  
 Or these 2 commands:  
  cp file1 file2 echo 'oranges' & gt; & Gt; File 2   
 The first file is copied to the new file 2, and then adds the word orange to file 2  
 here is another liner that does not use is; Neither & amp; Amp;  
  echo oranges | Cat file 1 - & gt; File2
