       [ function ] name () compound-command [redirection]
              This defines a function named name.  The reserved word function is optional.  If the function reserved word is supplied, the parentheses
              are optional.  The body of the function is the compound command compound-command (see Compound Commands above).  That command is usually
              a  list of commands between { and }, but may be any command listed under Compound Commands above.  compound-command is executed whenever
              name is specified as the name of a simple command.  Any redirections (see REDIRECTION below) specified when a function  is  defined  are
              performed  when  the  function is executed.  The exit status of a function definition is zero unless a syntax error occurs or a readonly
              function with the same name already exists.  When executed, the exit status of a function is the exit status of the  last  command  exe-
              cuted in the body.  (See FUNCTIONS below.)
