Fabric is just python there is no magic to it.
$ cat >fabfile1.py
import fabric
from fabric.api import run, env
import os
hostlist = '/tmp/hostlist'
if (os.path.exists(hostlist)):
env.hosts = list(file(hostlist).readlines())[:-1]
print(env.hosts)
def checkproc():
run('/bin/ps -elf |grep java')
$ fab checkproc -f fabfile1.py

Subject: [Fab-user] Dynamic hosts not supported by -H?
Hello all,
I'm trying to build a web app around a few fabric scripts, and I need to supply
a dynamic list of hosts to the scripts. I saw the -H switch, but it apparently
only works when env.hosts is defined in the fabric script. I also looked at
command-line kwargs for methods, but the methods won't even be executed without
env.hosts being defined. Can someone point me in the right direction?
Thanks,
