Interestingly, the LXD command line client is named.... lxc!
lxc image list ubuntu: # ubuntu: is officially supported image source
lxc image list images: # images: is an unsupported source
lxc image alias list images: # lists user-friendly names
This is intended for copying/pasting as the first comment to all Gist entries I create. It's unfortunate that GitHub doesn't support notifying creators and participants in the feedback process for Gists, but this is at least something I can do to let potential viewers know that I'm not intentionally ignoring them.
As of the time this Gist entry was created, GitHub does not support notifications for comments for mentions to Gist entries (see isaacs/github#21 for details). Please contact me via Twitter or file an issue in the deoren/leave-feedback repo (created for that very purpose) if you wish to receive a response for your feedback. Thank you in advance!
This is a story about how I tried to use Go for scripting. In this story, I’ll discuss the need for a Go script, how we would expect it to behave and the possible implementations; During the discussion I’ll deep dive to scripts, shells, and shebangs. Finally, we’ll discuss solutions that will make Go scripts work.
While python and bash are popular scripting languages, C, C++ and Java are not used for scripts at all, and some languages are somewhere in between.

In case you want to run ansible (or ansible-playbook) command against a set of hosts that makes sense only for one run,
you can don't bother to create one-time inventory file, but simply define a comma-separated list of hosts as argument of --invertory option (or its short form that's simply -i) as follows:
ansible --inventory=myhost1,myhost2,myhost3 all -m setup -a 'filter=*name*'(note that all in this command line stands for the target hostname)
If you have only one host to run your playbook against, your inventory string must ends with ,
