Reduce the size of the specified SCCS
files. This is done by
pruning selected deltas and combining those that remain, thereby
reconstructing the SCCS file. The default behavior prunes all but the
most recent delta in a particular branch and keeps only those
ancestors needed to preserve the tree structure. comb
produces a shell script on standard output. Actual reconstruction
of the SCCS files is done by running the script.
Preserve only those deltas whose SCCS IDs
are specified in the comma-separated
Use a hyphen (-) to supply a range; e.g., 1.3,2.1-2.5.
Access the reconstructed
file at the release number of the delta
that is created, instead of at the most recent ancestor. This option
may change the tree structure.
discard all deltas whose SCCS identification string is older than
Generate a shell script that calculates how much the file has been reduced in size. -s is useful as a preview of what comb will do when actually run.
