diffcopy

Copy modified files from sub directories into one target directory.

diffcopy checks which files have changed in a directory including its subdirectories based on the file name, file size and modification date.

These files are then copied to a target directory while retaining the original modification date.

./diffcopy test_data/input /test_data/output txt,dxf
