- combine SCCS deltas
comb [-os] [-csid-list] [-psid]s.filename...
comb generates a shell script (seesh(1)) that you can use toreconstruct the indicateds.files. This script is written to the standard output.
If a directory name is used in place of thes.filename argument,thecomb command applies to alls.files in that directory. Unreadables.filesproduce an error; processing continues with the next file (if any). The useof- as thes.filename argument indicates that the names of filesare to be read from the standard input, ones.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 topreserve the history.
The following options are supported:
For eachget -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 can decrease the size of the reconstructeds.file. It can also alter the shape of the delta tree of the original file.
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 is saved, before actually doing the combining.
Include the indicated list of deltas. All other deltas 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.
The SID of the oldest delta to be preserved.

comb might rearrange the shape of the tree of deltas. It mightnot save any space; in fact, it is possible for the reconstructedfile to actually be larger than the original.
