I extended Fabric to make it easier to specify the servers.
I call the modified Fabric FastHandle.

$ H=192.168.0.10
$ fab -H $H  -- hostname

$ fab -H 192.168.0.10  -- hostname
$ fab -H 192.168.0.10  test.test

$ echo 192.168.0.10 | fab  -- hostname
$ echo 192.168.0.10 | fab  test.test

$ H=192.168.0.10,192.168.0.11
$ fab -H $H  -- hostname

$ fab -H 192.168.0.10,192.168.0.11  -- hostname
$ fab -H 192.168.0.10,192.168.0.11  test.test

$ echo "192.168.0.10\n192.168.0.11" | fab  -- hostname
$ echo "192.168.0.10\n192.168.0.11" | fab  test.test

$ echo 192.168.0.10\\n192.168.0.11 | fab  -- hostname

$ vi tmp
192.168.0.1 test-web-01
192.168.0.1 test-web-02
$ cat tmp | fab  test.test

$ cat hosts/test
192.168.0.1 test-web-01
192.168.0.2 test-web-02
192.168.0.3 test-web-03
192.168.0.4 test-web-04
192.168.0.5 test-web-05
.....
192.168.0.98 test-web-98
192.168.0.99 test-web-99
$
$ fhghost.sh test-web hosts/test | fab  test.test

$ fhghost.sh  hosts/test | fab  test.test

Check $FHHOME/fhscripts/fhghost.sh
