09/10/87 trim_list, tls Syntax as a command: tls path -control_args Function: deletes selected records from the specified lister file. Because selection is required for trimming any lists, the select control argument must be used with this command. Arguments: path is the pathname of the lister file being trimmed. The suffix lister must be the last component of the lister file name; however, if path does not have a suffix of lister, one is assumed. Control arguments: -select STR, -sel STR specifies the records selected for deletion. This is a REQUIRED argument. -totals, -tt displays the number of records deleted. This is an OPTIONAL argument. Notes: The trim_list command sets the "lister" severity indicator. A severity of 2 is set when the trim is not performed, for some reason other than no records matching the selection expression, or the invocation of trim_list terminates abnormally. A severity of 1 is set when the selection expression matches no records. A severity of 0 is set when at least one record is trimmed and the command terminates normally. ----------------------------------------------------------- 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. . ----------------------------------------------------------- Permission to use, copy, modify, and distribute these programs and their documentation for any purpose and without fee is hereby granted,provided that the below copyright notice and historical background appear in all copies and that both the copyright notice and historical background and this permission notice appear in supporting documentation, and that the names of MIT, HIS, BULL or BULL HN not be used in advertising or publicity pertaining to distribution of the programs without specific prior written permission.
