shell rock-paper-scissors

We do a little game: rock-paper-scissors

First we look at the provisions of the rules:

1. The user inputs a value representative of stone scissors cloth, compared with the computer-generated random value

2. Only the user can exit the game won

  . 1 ! # / Bin / the bash
   2  
  . 3 arryas = (rock paper scissors)
   . 4  the while  to true 
  . 5  do 
  . 6 NUM = $ (($% the RANDOM . 3 ))
   . 7  
  . 8  
  . 9 Read -p " Enter Number: 1. 0. rock scissors 2 cloth " username
  10  
 . 11  echo -e " you are out of $ {arryas [$ username]} VS computer out arryas {$ [$ NUM]} \ n- " 
 12 is  
 13 is  dd = $ (($ username- $ NUM))
  14  IF [$ dd -eq . 1 -o $ dd -eq - 2 ]
 15  the then 
 16          echo  " you win " 
 . 17          Exit
  18 is  elif [$ dd -eq 0 ]
