bash: How do I selectively copy directories from one tree to another?

Question

My directory tree looks somewhat like this:

/Volumes/Data/TEMP/DROP
├───R1
│   ├───morestuff
│   │   └───stuff2
│   │       └───C.tool
│   └───stuff
│       ├───A.tool
│       └───B.Tool
└───R2
    ├───morestuff
    │   └───stuff2
    │       └───C.tool
    └───stuff
        ├───A.tool
        └───B.Tool

How do I copy the *.tool directories recursively from R1 to (overwrite) those in R2? My bash has about 20 years of rust on it.

Use `rsync` with an exclude filter, see http://man7.org/linux/man-pages/man1/rsync.1.html#INCLUDE/EXCLUDE_PATTERN_RULES — Maxim Egorushkin, Apr 09 '20 at 21:26

This will work (expanding on the idea of @Maxim Egorushkin)


# The trailing slash important in the next line
SOURCE=/Volumes/Data/TEMP/DROP/R1/
DEST=/Volumes/Data/TEMP/DROP/R2
rsync -zarv --include "*/" --include="*.tool" --exclude="*" "$SOURCE" "$DEST"
