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 has
been reduced in size.
-s
is useful as a preview of what
comb
will do when actually run.
