APPENDIX B FUNCTIONAL BREAKDOWN OP SELECTED MULTICS COMMANDS Even as a new user you will fast find need for many more commands than have been discussed in Part 1 and Part 2 of this Introduction to Multics. For that reason, this appendix provides you with a functional listing of Multics commands that are likely to become useful to you. The categories here are similar to those used in other Multics documentation. Ten of the seventeen categories normally used in the other manuals are used here along with a category which lists Multics' word processing commands. Some commands appear in more than one category just as they do in the functional groupings in other Multics manuals. Each category includes a description of how the commands in that group function. A complete description of the individual commands, except those used in word processing, is contained in the alphabetical listing of commands in MPM Commands. The word processing commands are described individually in the Multics WORDPRO Reference Guide. SELECTED COMMANDS LISTED BY FUNCTION Access to the System Access commands connect the terminal to a process. The hello command is more correctly called a preaccess request because it is used before a process has been set up; it repeats the greeting message that is printed whenever a terminal is first connected to the system. dial hello login logout Storage System, Creating and Editing Segments The commands in this category enable the user to create, edit, and format segments. create edm emacs indent program_interrupt qedx runoff runoff_abs Storage System, Segment Manipulation The commands in this category enable the user to compare and sort segments and adjust their sizes. Principally, they enable the user to manipulate a segment as a whole, copying it, truncating it, and moving it around in various ways in the storage system. archive compare copy delete link move sort_seg truncate unlink Storage System, Directory Manipulation The commands in this category enable the user to create, manipulate, and delete directories. copy_dir create_dir delete_dir link list move_dir rename status unlink Storage System, Access Control This category contains the commands that set, check, copy, delete, and list access to segments and directories. check_iacl copy_iacl copy_iacl_dir copy_iacl_seg delete_acl delete_iacl_dir delete_iacl_seg list_accessible list_acl list_not_accessible list_iacl_dir list_iacl_seg set_acl set_iacl_dir set_iacl_seg Storage System, Address Space Control Commands in this category enable the user to manipulate search paths and search rules and the working directory. This category also contains the new_proc command, which creates a new process with a new address space; this is equivalent to logging out and logging back in. add_search_paths add_search_rules change_default_wdir change_wdir delete_search_paths delete_search_rules get_system_search_rules initiate list_ref_names new_proc print_default_wdir print_proc_auth print_search_paths print_search_rules print_wdir set_search_paths set_search_rules where where_search_paths Command Level Environment Basically, commands in this category are designed to set up and control the environment in which other Multics commands are given. They enable the user to set the procedures by which other commands search for segments and directories, to manipulate the working directory, and to group commands on a command line or in a segment (even to abbreviate commands). abbrev add_search_paths add_search_rules answer change_default_wdir change_wdir delete_search_paths delete_search_rules do exec_com general_ready get_system_search_rules if line_length memo newjproc on print_default_wdir print_search_paths print_search_rules print_translator_search_rules print_wdir program_interrupt ready ready_off ready_on release set_search_paths set_search_rules start stop_run where_search_paths Communication Among Users The commands in this category give users facilities to send, receive, and store mail and short messages interactively with other users registered on Multics. accept_messages defer_messages delete_message immediate_messages print_auth_names print_mail print_messages read_mail send_mail send_message send_message_acknowledge send_message_express send_message_silent who Communication with the System With the commands in this category users can ask Multics what helpful information about the system operations is available on info segments and request help from particular info segments. Users can also find out how many people are using the system and who they are; in addition, users can request that the system's message of the day be printed at their terminal. check_info_segs help how_many_users move_abs_request print_motd who Control of Absentee Computations The commands in this category enter, move, and cancel requests to have work submitted by the user run by the system in the user's absence. cancel_abs_request cobol_abs enter_abs_request fortran_abs how_many_users list_abs_requests move_abs_request pl1_abs runoff_abs who Wordprocessing Commands in this category are used to create, edit, and format text and process lists of information. add_symbols add_dict_words change_symbols compose copy_list count_dict_words create_list create_wordlist delete_dict_words delete_symbols emacs expand_symbols find_dict_words find_symbols list_dict_words list_symbols locate_words merge_list option_symbols print_symbols_path print_wordlist process_list qedx retain_symbols revise_words show_symbols sort_list trim_list trim_wordlist use_symbols
