comb [ -o ] [ -s ] [ -c List | -p SID ] File
The comb command writes to standard output a shell procedure that can combine specified SCCS deltas (SIDs) or all deltas into one delta. You can reduce the size of your Source Code Control System (SCCS) file by running the resulting procedure on the file. To see how much the file will be reduced, run the comb program with the -s flag. If you specify a directory for the File value, the comb command performs the requested actions on all SCCS files (that is, those having an s. prefix). If you specify a - (minus) for the File value, the comb command reads standard input and interprets each line as the name of an SCCS file. The comb command continues to take input until it reads an end-of-file character.
If you do not specify any flags, the comb command preserves only leaf deltas and the minimal number of ancestors needed to preserve the tree.
Note: The comb command may rearrange the shape of the tree deltas. It may not save any space. In fact, it is possible for the reconstructed file to actually be larger than the original.
Note: Each flag or group of flags applies independently to each named file.
