=================
``File`` examples
=================
This page includes some simple examples of how to use the ``pyxrootd`` `File`
object to manipulate files on an ``xrootd`` server.
We'll use the following `File` object as a basis for the rest of the examples::
from XRootD import client
from XRootD.client.flags import OpenFlags
with client.File() as f:
f.open('root://someserver//tmp/eggs', OpenFlags.UPDATE)
f.write('green\neggs\nand\nham\n')
