comb(1) 						      General Commands Manual							   comb(1)

Name
       comb - combine delta versions of SCCS file

Syntax
       comb [-o] [-s] [-psid] [-clist] files

Description
       The  command  generates	a shell procedure which, when run, will reconstruct the given SCCS files.  For further information, see The recon-
       structed files are generally smaller than the original files.  The arguments may be specified in any order,  but  all  keyletter  arguments
       apply  to  all  named  SCCS  files.   If a directory is named, behaves as though each file in the directory were specified as a named file,
       except non-SCCS files (last component of the path name does not begin with s.)  and unreadable files, which are	silently  ignored.   If  a
       name of - is given, the standard input is read; each line of the standard input is taken to be the name of an SCCS file to be processed.

       The generated shell procedure is written on the standard output.

       Each  keyletter	argument  is  explained  as though only one named file is to be processed, but the effects of any keyletter argument apply
       independently to each named file.

Options
       -clist	 Preserves specified deltas.  See for the syntax of a list.  All other deltas are discarded.

       -o	 Causes the reconstructed file to be accessed at the release of the delta to be created.  Otherwise the reconstructed  file  would
		 be  accessed  at the most recent ancestor.  Use of the -o keyletter may decrease the size of the reconstructed SCCS file.  It may
		 also alter the shape of the delta tree of the original file.

       -pSID	 Indicates oldest delta to be preserved.  All older deltas are discarded in the reconstructed file.

       -s	 Generates a shell procedure which produces a report.  This report gives the file name, size (in blocks) after combining, original
		 size (also in blocks), and percentage change computed by:
							      100 * (original - combined) / original
		 It  is   recommended  that  before any SCCS files are actually combined, one should use this option to determine exactly how much
		 space is saved by the combining process.

       If no keyletter arguments are specified, will preserve only leaf deltas and the minimal number of ancestors needed to preserve the tree.

Restrictions
       The command 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 actually be larger than the original.

Diagnostics
       See for explanations.

Files
       s.COMB	     The name of the reconstructed SCCS file.
       comb?????     Temporary.
