2nd: In post #8, it was pointed out that the filename matching pattern I suggested in post #4 has a Y3K problem (i.e., would stop working in January, 3000). Using the filename matching pattern shown above (i.e., 2018*.tar.gz, the code will stop working in January, 2019. Do you really want to use a pattern that only matches files created this year?
regarding 2 nd point, obviously I need this to work after 2018 as well Smilie .

SHAPE_TAR(1)						      General Commands Manual						      SHAPE_TAR(1)

NAME
shape_tar - shapeTools RMS bundle up subsystem in a tar or shar archive SYNOPSIS
shape tar[VERSIONS=<version_selection_rule>] [ARCHIVE=<filename>] shape shar[VERSIONS=<version_selection_rule>] [ARCHIVE=<filename>] DESCRIPTION
Shape tar and shape shar create a tar or a shar archive containing all source components of the current node in the system tree. All source components listed in the COMPONENTS macro in the Makefile and the release identification file (VERSIONFILE) are written to the archive. Components of subsystems are not included in the archive file. The VERSIONS macro may be set to specify a version selection rule to be active during archive file creation. Default is most_recent, selecting the most recent version of each component. See shape_stdrul(7) or the $(SHAPELIBPATH)/stdrules for other possible settings. You may also use self defined version selection rules as VERSIONS. ARCHIVE is the base name of the file where the output shall be written to. Default is $(SUBSYSTEMNAME). The output file gets the filename extension .tar (resp. .shar). When ARCHIVE=- is given, data will be written to standard output. SEE ALSO
shape_RMS(1), shape_stdrul(7) FILES
$(SUBSYSTEMNAME).tar $(SUBSYSTEMNAME).shar 1.6.119 SHAPE_TAR(1)
