NAME
       sccs-comb, comb - combine SCCS deltas

SYNOPSIS
       /usr/ccs/bin/comb [-os] [-csid-list] [-psid] s.filename...

DESCRIPTION
       comb  generates	a  shell script	(see sh(1)) that you can use to	recon-
       struct the indicated s.files.  This script is written to	 the  standard
       output.

       If  a  directory	 name is used in place of the s.filename argument, the
       comb command applies to	all  s.files  in  that	directory.  Unreadable
       s.files	produce	 an error; processing continues	with the next file (if
       any). The use of	`-' as the  s.filename	argument  indicates  that  the
       names  of  files	are to be read from the	standard input,	one s.file per
       line.

       If no options are specified, comb preserves only	the most recent	(leaf)
       delta  in  a branch, and	the minimal number of ancestors	needed to pre-
       serve the history.

OPTIONS
       The following options are supported:

       - o   For each `get -e' generated, access the reconstructed file	at the
	     release  of the delta to be created. Otherwise, the reconstructed
	     file is accessed at the most recent ancestor. The use of  -o  may
	     decrease  the size	of the reconstructed s.file. It	may also alter
	     the shape of the delta tree of the	original file.

       -s    Generate scripts to  gather  statistics,  rather  than  combining
	     deltas.  When  run, the shell scripts report: the file name, size
	     (in blocks) after combining, original size	(also in blocks),  and
	     the percentage size change, computed by the formula:

	     100 * ( original -	combined ) / original

	     This  option  can	be  used  to  calculate	the space that will be
	     saved, before actually doing the combining.

       -csid-list
	     Include the indicated list	of deltas.  All	other deltas are omit-
	     ted. sid-list is a	comma-separated	list of	SCCS delta IDs (SIDs).
	     To	specify	a range	of deltas, use a `-' separator	instead	 of  a
	     comma, between two	SIDs in	the list.

       -pSID The SID of	the oldest delta to be preserved.

FILES
	s.COMB
	     reconstructed  SCCS file

       comb?????
	     temporary file

DIAGNOSTICS
       Use the SCCS help command for explanations (see sccs-help(1)).

BUGS
       comb  may  rearrange  the shape of the tree of deltas.  It may not save
       any space; in fact, it is possible for the reconstructed	file to	 actu-
       ally be larger than the original.
