 4.3 Specifying Program Options
 ==============================
 
 You can provide options for MySQL programs in several ways:
 
    * On the command line following the program name. This is most
      common for options that apply to a specific invocation of the
      program.
 
    * In an option file that the program reads when it starts. This is
      common for options that you want the program to use each time it
      runs.
 
    * In environment variables. These are useful for options that you
      want to apply each time the program runs, although in practice
      Multiple Unix servers:: discusses one situation in which
      environment variables can be very helpful. It describes a handy
      technique that uses such variables to specify the TCP/IP port
      number and Unix socket file for both the server and client
      programs.)
 
 
 MySQL programs determine which options are given first by examining
 environment variables, then option files, and then the command line.
 If an option is specified multiple times, the last occurrence takes
 precedence.  This means that environment variables have the lowest
 precedence and command-line options the highest.
 
 You can take advantage of the way that MySQL programs process options by
 specifying the default values for a program's options in an option
 file. Then you need not type them each time you run the program, but
 can override the defaults if necessary by using command-line options.
