Python makes things easy, from a certain point of view. You have to think
that Python is a program language and not a command language (like Bourne
Others have a number of solutions that will move your files with os.walk and
os.path.walk. They are nice, but sometimes it's better to traverse the tree
individually. Also, you didn't specify if the destination "folder"
structure already existed, or if it will need to be created (which cp -r
will do). The following should handle that case for you:
import fnmatch, os
def movetree(srcdir, dstdir, pattern=None):
# dstdir must exist first
srcnames = os.listdir(srcdir)
for name in srcnames:
srcfname = os.path.join(srcdir, name)
dstfname = os.path.join(dstdir, name)
elif pattern is None or fnmatch.fnmatch(name, pattern):
You could do the same with os.walk or os.path.walk, but the recursive nature
of the function takes care of itself a bit better, IMO.
There's so many different worlds,
So many different suns.
And we have just one world,
But we live in different ones.
