command lets the user try to reduce the size of an SCCS file.
It generates a shell procedure
on the standard output,
which reconstructs the file by
discarding unwanted deltas and combining other specified deltas.
(It is not recommended that comb be used as a matter of routine.)
In the absence of any key letters, comb
preserves only leaf deltas and the minimum number of
ancestor deltas necessary to preserve the shape of an SCCS tree.
The effect of this is to eliminate middle deltas on
the trunk and on all branches of the tree.
``Extended branching concept''
deltas 1.2, 126.96.36.199, 1.4, and 2.1 would be eliminated.
Some of the key letters options used with this command are as follows:
The shell procedure generated by comb is not
guaranteed to save space.
A reconstructed file may even be larger than the original.
Note, too, that the shape of an SCCS file tree can be altered by
the reconstruction process.
generates a shell procedure
that produces a report of the percentage space (if any) the user will save.
This is often useful as an advance step.
specifies the oldest delta the user wants preserved.
specifies a list
of deltas the user wants preserved.
All other deltas are discarded.
