Path: uunet!rs From: rs@uunet.UU.NET (Rich Salz) Newsgroups: comp.sources.unix Subject: v11i034: The 'less' pager, Part02/03 Message-ID: <1499@uunet.UU.NET> Date: 10 Sep 87 03:44:54 GMT Organization: UUNET Communications Services, Arlington, VA Lines: 1532 Approved: rs@uunet.UU.NET Submitted-by: sun!intsc!convgt!mark@uunet.UU.NET Posting-number: Volume 11, Issue 34 Archive-name: less3/Part02 [ Sorry about (a) the lag and (b) not posting this part first. It's been both Labor Day and Moving Day around these parts. --r$ ] This is the latest version (v.73) of less. Less is a pager, like more or pg, only with more features then both of them. Unpack and read the README file for installation instructions. Changes since the last posted version (v.61) are: * Now allows !! to repeat previous shell escape. * Now allows % as shorthand for the current file name in shell escapes. * Now allows # in Examine command to examine previous file, and return to the same place in that file. * Changed -p option to -C, and added -c for compatibility with "more". * -e flag now exits immediately after displaying if file is less than a screenful. * Added -E (like -e, but exit FIRST time you hit end-of-file). * Added -L (like -l, but unconditionally overwrite existing log file). * Can now change number-valued command line options from within less (via the "-" command). * Added support for SIGWINCH (window size change signal in BSD 4.3). * Added similar support for SIGWIND (same thing on the AT&T Unix PC). * Better error messages if input cannot be opened or is not a "regular" file. * Changed help command from h to H to avoid accidentally entering help. * Fixed bug which caused problems on terminals with more than 24 lines.
