02/15/85  list_ref_names, lrn

Syntax as a command:  lrn paths {-control_args}


Function: lists the reference names associated with a given segment.
You can specify segments by either pathname or segment number.


Arguments:
paths
   are the segment numbers and pathnames of segments known in your
   process.  They can be "-name STR" ("-nm STR") to specify a pathname
   that begins with a minus sign or looks like a segment number.  If
   you supply no paths, information for all segments known in your
   process is printed, excluding those known in ring 0.


Control arguments:
-all, -a
   prints information for all known segments, including ring 0
   segments.  It is equivalent to -from 0.
-brief, -bf
   suppresses printing of the reference names for the entire execution
   of the command.


-from N, -fm N
   allows you to specify a range of segment numbers.  You can use it
   with -to; information for the segment numbers in this range is
   printed.  If you don't select -to, the highest used segment number
   is assumed.
-to
   allows you to specify a range of segment numbers.  If you supply no
   -from, the segment number of the first segment not in ring 0 is
   assumed.


Notes: You can mixed all the above arguments (segment specifiers and
control arguments).  For example, in the command line
   lrn  156 -from 230 path_one
information is printed for segment 156, all segments from 230 on, and
the segment whose pathname is path_one.  In the default condition, when
called with no arguments, list_ref_names prints information on all
segments that are not in ring 0.

Historical Background

This edition of the Multics software materials and documentation is provided and donated
to Massachusetts Institute of Technology by Group BULL including BULL HN Information Systems Inc. 
as a contribution to computer science knowledge.  
This donation is made also to give evidence of the common contributions of Massachusetts Institute of Technology,
Bell Laboratories, General Electric, Honeywell Information Systems Inc., Honeywell BULL Inc., Groupe BULL
and BULL HN Information Systems Inc. to the development of this operating system. 
Multics development was initiated by Massachusetts Institute of Technology Project MAC (1963-1970),
renamed the MIT Laboratory for Computer Science and Artificial Intelligence in the mid 1970s, under the leadership
of Professor Fernando Jose Corbato. Users consider that Multics provided the best software architecture 
for managing computer hardware properly and for executing programs. Many subsequent operating systems 
incorporated Multics principles.
Multics was distributed in 1975 to 2000 by Group Bull in Europe , and in the U.S. by Bull HN Information Systems Inc., 
as successor in interest by change in name only to Honeywell Bull Inc. and Honeywell Information Systems Inc. .
