say we have two folders:
mkdir foldera folderb
touch foldera/a.txt
touch foldera/b.txt
touch foldera/.e.txt
touch folderb/c.txt
touch folderb/d.txt
this produces
- foldera
- a.txt
- b.txt
- .e.txt
- folderb
- c.txt
- d.txt
then
rsync -haviP foldera folderb
will create
- folderb
- c.txt
- d.txt
- foldera
- a.txt
- b.txt
- .e.txt
however,
rsync -haviP foldera/ folderb
will result in
- foldera
- a.txt
- b.txt
- c.txt
- d.txt
- .e.txt
and
rsync -haviP foldera/ folderb/
produces the same results
rsync -haviP --delete foldera/ folderb
will result in
- foldera
- a.txt
- b.txt
- .e.txt
rsync -haviP foldera/* folderb
will result in
- foldera
- a.txt
- b.txt
- c.txt
- d.txt
