Copying changed files in a tree

Ruby
1

Do any of the ruby build tools (rake, rant, somethingelse?) support
the task “copy all the files that have changed since the last time i
ran the copy task” across an entire directory tree? e.g. if I have the
structure

foo/
foo/file1
foo/file2
foo/bar/
foo/bar/file3

the first time i run rake copy, it should copy the entire tree over.
Now say I touch foo/bar/file3, and rerun rake copy, it should only
copy that file over.

use rsync. it rules.

good point :slight_smile: i was trying too hard for a pure ruby solution.

GNU cp also has some nice options to deal with this (from memory, -a and
-u).

Kind regards
