I just want to find out what is the difference between 

```
cp -R $rootpath/vgcore/core/src/geom/*.* $destpath/geom_src

```

,

```
cp -R $rootpath/vgcore/core/src/geom/* $destpath/geom_src

```

,

```
cp -R $rootpath/vgcore/core/src/geom $destpath/geom_src

```

and 

```
cp -R $rootpath/vgcore/core/src/geom/ $destpath/geom_src

```

Let's say we have one subdir in geom, say alg with files in it

1. In the case of one, would only all the files be copied from geom and alg and put into geom\_src? So the dir structure of the source will be ignored?
2. all the files from geom and all the files from alg + alg itself will be copied over retaining the subdir structure?
3. sames as 2?
4. sames as 2 & 3?

Sorry, don't have a test Linux machine handy to test this myself.

Thanks.
