SYNOPSIS
     builtin [-options]	[args ...]

DESCRIPTION
     Shell builtin commands are	commands that can be executed within the run-
     ning shell's process.  Note that, in the case of csh(1) builtin commands,
     the command is executed in	a subshell if it occurs	as any component of a
     pipeline except the last.

     If	a command specified to the shell contains a slash ``/'', the shell
     will not execute a	builtin	command, even if the last component of the
     specified command matches the name	of a builtin command.  Thus, while
     specifying	``echo'' causes	a builtin command to be	executed under shells
     that support the builtin echo command, specifying ``/bin/echo'' or
     ``./echo''	does not.

     While some	builtin	commands may exist in more than	one shell, their oper-
     ation may be different under each shell which supports them.  Below is a
     table which lists shell builtin commands, the standard shells that	sup-
     port them and whether they	exist as standalone utilities.

     Only builtin commands for the csh(1) and sh(1) shells are listed here.
     Consult the appropriate manual page for details on	the operation of any
     given builtin command under those shells.	Users of other shells will
     need to consult the documentation supplied	with the other shells.
