Scenario:
ssh to remote hosts and run commands in parallel by threads.
Note: this example requires sshscript version >= 1.1.12

# If the localhost can connect host-b, host-c directly,
# We don't need to connect bridge host, just comment-out the next line.
$.connect('user@host-a')
$ hostname
print('connected to',$.stdout)
# if you are interested of its outupt
# os.environ['VERBOSE'] = '1'
def job(account,pkey,ret):
# this example shows how to load private key for authentication
$.connect(account,pkey=pkey)
# executing command
$ hostname
ret['hostname'] = $.stdout
# executing command
$ date
ret['date'] = $.stdout
$.close()
pkey = $.pkey('/home/user/.ssh/id_rsa')
# invoking thread-1
ret1 = {}

# invoking thread-2
ret2 = {}
t2 = $.thread(target=job,args=('user@host-c',pkey, ret2))
t1.start()
