Python. Fabric is a Python library and command-line tool for streamlining the use of SSH for application deployment or systems administration tasks. Fabric is very simple and powerful and can help to automate repetitive command-line tasks. This approach can save time by automating your entire workflow.
More specifically, Fabric is: A tool that lets you execute arbitrary Python functions via the command line; A library of subroutines (built on top of a lower-level library) to make executing shell commands over SSH easy and Pythonic.
fab uses Python's optparse library, meaning that it honors typical Linux or GNU style short and long options, as well as freely mixing options and arguments. E.g. fab task1 -H hostname task2 -i path/to/keyfile is just as valid as the more straightforward fab -H hostname -i path/to/keyfile task1 task2 .
I know you've asked about password but wouldn't it better to configure the system so that you can doing fabric (i.e. SSH) without password?
For this, on local machine do:
ssh-keygen and agree with all defaults (if you have no reasons do otherwise)cat ~/.ssh/id_rsa.pub and copy that keyOn remote machine:
mkdir ~/.ssh && chmod 700 ~/.sshtouch ~/.ssh/authorized_keys2 && chmod 600 ~/.ssh/authorized_keys2authorized_keys2 From now your remote machine “trusts” your local machine and allows logging it in without password. Handy.
