Options:
-h, --help show this help message and exit
-l, --list print list of possible commands and exit
-H HOSTS, --hosts=HOSTS
comma-separated list of hosts to operate on
-f PATH, --fabfile=PATH
python module file to import, e.g. '../other.py'
-i PATH path to SSH private key file. May be repeated.
-u USER, --user=USER username to use when connecting to remote hosts
--skip-bad-hosts skip over hosts that can't be reached
--hide=LEVELS comma-separated list of output levels to hide
Ex) --hide=running
# fab -l #print list of possible commands and exit # fab --list
# fab -H HOST -- COMMAND # fab -H server1 -- hostname # fab -H server1, server2, server3 -- hostname
Default configuration file is fabfile.py.
# fab -H 192.168.1.1 mkdir # fab -H 192.168.1.1,192.168.1.2 mkdir # fab -u USER -i KEY -H HOST install_git
# fab -H HOST -f myfabfile.py test
# echo xx.xx.xx.xx | fab -- hostname # echo xx.xx.xx.xx | fab -- sudo cat /etc/shadow # echo xx.xx.xx.xx | fab -f myfabfile.py test
