6 sccs-comb, comb - combine SCCS deltas
7
9 comb [-os] [-csid-list] [-psid] s.filename...

11
13 comb generates a shell script (see sh(1)) that you can use to recon‐
14 struct the indicated s.files. This script is written to the standard
15 output.
16
17
18 If a directory name is used in place of the s.filename argument, the
19 comb command applies to all s.files in that directory. Unreadable
20 s.files produce an error; processing continues with the next file (if
21 any). The use of `−' as the s.filename argument indicates that the
22 names of files are to be read from the standard input, one s.file per
23 line.
24
25
26 If no options are specified, comb preserves only the most recent (leaf)
27 delta in a branch, and the minimal number of ancestors needed to pre‐
28 serve the history.
29
31 The following options are supported:
32
33 -o For each `get -e' generated, access the reconstructed
34 file at the release of the delta to be created. Other‐
35 wise, the reconstructed file is accessed at the most
36 recent ancestor. The use of -o can decrease the size of
37 the reconstructed s.file. It can also alter the shape of
38 the delta tree of the original file.
39
40
41 -s Generate scripts to gather statistics, rather than com‐
42 bining deltas. When run, the shell scripts report: the
43 file name, size (in blocks) after combining, original
44 size (also in blocks), and the percentage size change,
45 computed by the formula:
46
47 100 * ( original − combined ) / original
48
49 This option can be used to calculate the space that is
50 saved, before actually doing the combining.
51
52
53 -csid-list Include the indicated list of deltas. All other deltas
54 are omitted. sid-list is a comma-separated list of SCCS
55 delta IDs (SIDs). To specify a range of deltas, use a `−'
56 separator instead of a comma, between two SIDs in the
57 list.
58
59
60 -pSID The SID of the oldest delta to be preserved.

91 comb might rearrange the shape of the tree of deltas. It might not save
92 any space; in fact, it is possible for the reconstructed file to actu‐
93 ally be larger than the original.
