Exclude node_modules in timemachine

command.sh

find `pwd` -type d -maxdepth 3 -name 'node_modules' | xargs -n 1 tmutil addexclusion

Also, it appears that tmutil addexclusion supports multiple args:

$ mkdir -p {foo,bar}
$ ls
bar  foo
$ xattr *
$
$ tmutil addexclusion ./foo ./bar
$ xattr *
bar: com.apple.metadata:com_apple_backup_excludeItem
foo: com.apple.metadata:com_apple_backup_excludeItem

which means that many of the above commands could probably be done much more efficiently with find ... -exec tmutil addexclusion {} +, which collects arguments and runs the command once with collected arguments, as opposed to \; or piping to xargs / parallel, which will be separate invocations of tmutil.

EDIT: The equivalent for fd is --exec-batch
