Thanks for pointing to https://github.com/juju/utils/blob/master/fs/copy.go
I was testing Copy function that recursively copies directories. I am able
to copy first level of files and it creates directories. It fails to copy
the contents within those directories.
func Copy(src, dst string) error {...}
Error
$ triggerCopyCommand.go
lstat sd101-jvm/target/*.jar: no such file or directory ---> This is OK. As
it does not exists.
lstat sd101-python/sd101/*: no such file or directory ---> This exists in
the directory from which Copy is invoked.
lstat sd101-r/sd101/*: no such file or directory ---> This exists.
lstat sd101-shell/sd101/*: no such file or directory ---> This exists.
$ ls sd101-python/sd101/
__init__.py prepare setup.py train
$
$ ls sd101-r/sd101/
helloWorld.R
$ ls sd101-shell/sd101/
ls: sd101-shell/sd101/: No such file or directory
$
Any suggestions ?
Can this code be
replicated https://github.com/juju/utils/blob/master/fs/copy.go ? Or do you
recommend using it as a library ?
