comb
[
options
]
files
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.
-c
list
Preserve only those deltas whose SCCS IDs are specified in the comma-separated list
. Use a hyphen (-) to supply a range; e.g., 1.3,2.1-2.5
.
-o
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.
-p
sid
In reconstructing file
, discard all deltas whose SCCS identification string is older than sid
.
-s
Generate a shell script that calculates how much the file will be reduced in size. -s
is useful as a preview of what comb
does when actually run.
