4 Shell Builtin Commands
************************

* Bourne Shell Builtins
Builtin commands inherited from the Bourne Shell.
* Bash Builtins
Table of builtins specific to Bash.
* The Set Builtin
This builtin is so overloaded it deserves its own section.
* Special Builtins
Builtin commands classified specially by POSIX.
Builtin commands are contained within the shell itself.  When the name
of a builtin command is used as the first word of a simple command
(Note: Simple Commands), the shell executes the command directly,
without invoking another program.  Builtin commands are necessary to
implement functionality impossible or inconvenient to obtain with
separate utilities.

   This section briefly describes the builtins which Bash inherits from
the Bourne Shell, as well as the builtin commands which are unique to or
have been extended in Bash.

   Several builtin commands are described in other chapters: builtin
commands which provide the Bash interface to the job control facilities
(Note: Job Control Builtins), the directory stack (Note: Directory
Stack Builtins), the command history (Note: Bash History Builtins),
and the programmable completion facilities (Note: Programmable
Completion Builtins).

   Many of the builtins have been extended by POSIX or Bash.

   Unless otherwise noted, each builtin command documented as accepting
options preceded by '-' accepts '--' to signify the end of the options.
For example, the ':', 'true', 'false', and 'test' builtins do not accept
options.
