     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 ``eecchhoo'' causes a builtin command to be executed under shells
     that support the builtin echo command, specifying ``_/_b_i_n_/_e_c_h_o'' or
     ``_._/_e_c_h_o'' 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.
