I've been playing with jq, and I've been having a hard time finding examples of how it works with output from a service like AWS (which I use a lot).
Here is one I use a lot with vagrant-ec2.
When we're launching and killing a lot of instances, the AWS API is the only way to track down which instances are live, ready, dead, etc.
To find instances that are tagged with e.g. {"Key" = "Name", "Value" = "Web-00'} in the middle of a vagrant dev cycle, or a prod launch/replace cycle, you can do something like this:
1982 - Run to the hills | |
1982 - The number of the beast | |
1983 - The Trooper | |
1984 - Aces High | |
1986 - Wasted Years | |
1992 - Fear of the dark | |
1982 - Hallowed be thy name |
1969 - Led Zeppelin - Whole Lotta Love | |
1970 - Led Zeppelin - Immigrant Song | |
1971 - Led Zeppelin - Stairway To Heaven | |
1971 - Led Zeppelin - Black Dog | |
1971 - Led Zeppelin - Misty Mountain Hop | |
1975 - Led Zeppelin - Kashmir |

In Linux KVM we use sparse file format called qcow
and qcow2
for disk images.
Sometimes we need to mount a qcow2 disk images of a guest devices on to your host server.
We need to do this to salvage a file, reset password of root user, or troubleshoot a faulty disk image.
We can use this dcumentation to do mount a Linux KVM guest qcow2 disk.
