shape_patch - shapeTools RMS generate patch file
shape patch OLDRELEASE=<name1> NEWRELEASE=<name2> [PATCHFILE=<filename>]
Shape patch generates a patch file for updating $(OLDRELEASE) to $(NEWRELEASE). Both releases are identified by release names associated with the macros OLD-/NEWRELEASE on the command line. Valid release names are those generated by any of the shape_RMS (pre-)release building procedures (see shape_releas(1)). Performing 'vl -all' with the release identification file as argument usually gives a good overview of existing release names. Patch generation happens recursively over all subsystems being part of the current node. Hence, triggering shape patch from the top node of the central source repository creates a patch file for the whole system. The output of shape patch is stored in a file named <name1>+2+<name2>.pat. When the PATCHFILE macro is set on the command line, $(PATCHFILE) is taken as output file name instead. Defining PATCHFILE=- on the command line causes the patch to be written to standard output. Note: For patches invoking multiple subsystems, $(PATCHFILE) should be set to an absolute pathname. If not, the patch generation procedure will leave an equally named patch file for each visited subsystem. The patch is constructed using the vdiff(1) command and can be applied to any installation of $(OLDRELEASE) by invoking patch(1).
On System V machines, the generated patch file name will almost certainly exceed the 14 characters filename length limit.
