ters.
shell_esc = icl | abort :
This parameter can be used to alter the behaviour of the Erlang shell when ^G is pressed.
restricted_shell = module() :
This parameter can be used to run the Erlang shell in restricted mode.
shell_catch_exception = bool() :
This parameter can be used to set the exception handling of the Erlang shell's evaluator process.
shell_history_length = integer() >= 0 :
This parameter can be used to determine how many commands are saved by the Erlang shell.
shell_prompt_func = {Mod, Func} | default :
where
* Mod = atom()
* Func = atom()
This parameter can be used to set a customized Erlang shell prompt function.
shell_saved_results = integer() >= 0 :

erl_boot_server(3erl) Erlang Module Definition erl_boot_server(3erl)NAME
erl_boot_server - Boot Server for Other Erlang Machines
DESCRIPTION
This server is used to assist diskless Erlang nodes which fetch all Erlang code from another machine.
This server is used to fetch all code, including the start script, if an Erlang runtime system is started with the -loader inet command
line flag. All hosts specified with the -hosts Host command line flag must have one instance of this server running.
This server can be started with the kernel configuration parameter start_boot_server .
The erl_boot_server can both read regular files as well as files in archives. See code(3erl) and erl_prim_loader(3erl) .
Warning:
The support for loading of code from archive files is experimental. The sole purpose of releasing it before it is ready is to obtain early
feedback. The file format, semantics, interfaces etc. may be changed in a future release.
