under Unix, it's the shell that expands glob patterns. individual commands
usually don't know anything about such patterns.
so if you run the "cp" command directly, it will look for a single file named
"subdir/*.jpg". if you run it via the shell, it will get a list of matching files
from the shell.
here's a corresponding pure-python solution, btw:
import glob, shutil
for file in glob.glob("subdir/*.jpg"):
shutil.copy(file, "othersubdir")
