bash: Simple Commands

 
 3.2.1 Simple Commands
 ---------------------
 
 A simple command is the kind of command encountered most often.  It's
 just a sequence of words separated by 'blank's, terminated by one of the
 shell's control operators (Definitions).  The first word
 generally specifies a command to be executed, with the rest of the words
 being that command's arguments.
 
    The return status (Exit Status) of a simple command is its
 exit status as provided by the POSIX 1003.1 'waitpid' function, or 128+N
 if the command was terminated by signal N.
