  5. /bin/sh bug
  6. With sh if you say
  7.  
  8.     $ var=value command
  9.  
  10. then "var" is temporarily exported into the environment
  11. for the execution of "command". But you cannot say
  12.  
  13.     $ exec var=value command
  14.  
  15. because the silly shell tries to execute "var=value", and
  16. if you say
  17.  
  18.     $ var=value exec command
  19.  
  20. then "command" gets executed but "var" doesn't get exported.
