Thank you for yourreply, but I'mstilla little trouble.
Because there is a directory d in 1/a/b/c.  So the command you recommend did 
not work well.
 
opensuse113:/home/test_install # install -d 2/a/b/c && install 1/a/b/c/* 2/a/b/c
install: omitting directory `1/a/b/c/d'

How can I do please?
Thanks.
