Fabric doesn't run on the remote machine, it invokes commands on the
remote machine.

If you want to use glob to find the files, you need to have a python
script on the remote machine that contains your glob code e.g.

#!/bin/python
# /home/yungwei/last_modified.py
last_mod_file = ""
for file in glob.glob("/var/lib/mysql-backup/*"):
   if (file > last_mod_file):
       last_mod_file = file
print last_mod_file,"is the last modified."

Then run that script (provided you already have Python installed on
the remote machine) via fabric.operations.run or
fabric.operations.sudo. For example:

from fabric.operations import run
env.hosts = ['address@hidden']

def print_latest_model():
   run('~/last_modified.py')

(NB: I haven't tested this code, just pointing you in the right direction)

The docs at http://docs.fabfile.org/0.9.2/index.html contain this
information, you should familiarize yourself with them to learn more
about Fabric.
