sccs-comb(1)
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 reconstruct the indicated s.files. This script is writ-
ten to the standard output.
If a directory name is used in place of the s.filename argu-
ment, the comb command applies to all s.files in that direc-
tory. Unreadable s.files produce an error; processing con-
tinues 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 preserve 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. Other-
wise, 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, ori-
ginal 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 del-
tas are omitted. 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.

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