I bet your sub folders did not have a dot in them.
cp -R * //media/sda1
* matches everything. *.* matches with a . somewhere between 2 sets of everythings.
I have no idea why *.* works the way it does in dos.
note: file name globbing is a bash/shell thing. most commands have no concept
of wild cards, they just want a list of parameters. If you look closely at the
cp syntax:
Copy SOURCE to DEST, or multiple SOURCE(s) to DIRECTORY.
multiple sources is done by specifying each one, not by suppling a wild card.
This probably still doesn't jive, so lets look at some examples:
carl (AT) dell29:~$ echo *
a b backups batcave1 DOT flw batcave1.flw~ bin...qemu resume.html sound.wav
sources.list.gutsy.cached Splash.aspx src temp
The echo command does not know about file names or wild cards, it just echos
what ever parameters you give it. it echoed all that stuff, because bash
expanded the * to the list of files in the dir, and passed that to echo.
carl@dell29:~$ echo *.*
batcave1.flw batcave1.flw~ ... resume.html sound.wav sources.list.gutsy.cached
Splash.aspx
if I wanted to copy those files to /tmp, I could do:
cp batcave1.flw batcave1.flw~ resume.html sound.wav sources.list.gutsy.cached
Splash.aspx /tmp
or, cp *.* /tmp
and one last trick: to 'test' commands to see what they will see, but not
actually execute:
$ echo cp *.* /tmp
cp batcave1.flw batcave1.flw~ resume.html sound.wav sources.list.gutsy.cached
Splash.aspx /tmp
