12 Control arguments:
13 -abbrev, -ab
14 enables abbreviation expansion and editing of request lines.
15 -iteration, -it

22 parentheses in the request line are interpreted literally i.e.
23 they do not cause request line iteration. Default

26 -no_prompt, -npmt
27 turns off prompting of strings. This control argument can be
28 overridden later see set_mode request. Default is prompt
29 -no_start_up, -nsu
30 specifies that the subsystem start_up exec_com is not to be
31 executed.
32 -profile path, -pf path
33 specifies the pathname of the profile used for abbreviation
34 expansion. A profile suffix must be the last component to path;
35 however, the suffix need not be supplied in the command line. This
36 control argument implies -abbrev.
37 -prompt STR
38 sets the prompting string used by linus to STR. If STR contains
39 embedded blanks, it must be enclosed in quotes. Default linus
40 prompt is "linus:".
41

43 -request STR, -rq STR
44 executes STR as a linus request line before entering the request
45 loop.
46 -start_up, -su
47 specifies that the subsystem start_up exec_com "start_up.lec" is
48 executed prior to entering the request loop. The start_up is
49 searched for in the user's home directory, project directory, and
50 then >site. Default

53 Notes: By default, linus prompts the user whenever input is expected
54 the string "linus:" is displayed at linus request level. Refer to
55 the description of the set_mode request for information on how to turn
56 off prompting.
57
58 Multics program_interrupt conditions are recognized and handled by
59 linus. Thus, the user may interrupt any request and resume the linus
60 session by invoking the Multics program_interrupt command. After the
61 program_interrupt command, linus waits for the user to type further
62 requests.
63
64
65 There is no data base creation facility within linus. Those users who
66 wish to create their own data base should refer to Section 3 of the
67 Multics Logical Inquiry and Update System Reference Manual AZ49 for
68 information on the creation of an MRDS data base.
