Find copied and modified (duped and rigged) files between two related folder hierarchies which are contained in git repositories. Prints current file SHA-256 along with its latest matching commit hash as seen in the git repository of the first folder specified in the argument list (if available).
- Some version of git which isn't ancient. Tested with git
2.17.1. - Go 1.13.
go get -u github.com/setlog/duperig
git checkout the correct revisions of the projects in which you want to compare folder hierarchies, then use the command like so:
duperig path/to/folder/from/which/files/were/copied path/to/folder/to/which/files/were/copied
duperig projects/thingamajig_base/src/main/java/com/pany projects/thingamajig_special/src/main/java/com/pany
