This is a new, stable release with a number of UX and rendering issues fixed by @ms140569. Thanks!

Changelog

4033a22 fixes install instructions
fe31bd9 fixes version rendering issue
f7f778a fixes issue #2
ebb342d sorts default output by namespace ID
381953e changes to use full terminal width for default output

Besides some clean up and more detailed docs, this release mainly introduces one new feature: monitoring. It's a bit like top, you can specify a process along with cgroup control files to be watched, for example cinf --mon 12796:memory.usage_in_bytes and you'll get a live updated view. See also details in the walkthrough.

This release is a big step forward as it introduces two new ways that you can explore namespaces and cgroups:

• a sort of reverse lookup: cinf --pid 9422 lists all the namespaces the process with PID 9422 is in
• a cgroups details query: cinf --cgroup 5:9422 lists consumption details of the cgroup of the hierarchy ID 5 (which happens to be mapped to memory on my test system) for the process with PID 9422

Other things done are a consolidation of the CLI arguments (it used to be --namespace as the default, implicit argument) and some more docs around cgroups.

This release has some internal improvements (refactoring) as well as the following user-facing changes:

• Improves the listing of user per namespace (now, all unique UIDs are shown, not only the first)
• Adds CMD column (from /proc/$PID/cmdline)
• Improves docs (internal and user-facing)

This is the very first release of cinfand I hope it's useful for you. It's Linux only (I tested under Ubuntu 14.04) and it only supports two things for now: list all namespaces and dig into a specific namespace.

If you find a bug or have a suggestion how to extend cinf, raise an issue here, please.
