Several `abra` commands can output JSON formatted tables, and can thus be queried and filtered with the tool [jq](https://stedolan.github.io/jq/ "jq JSON Query tool"). We can also format these outputs with [tv](https://github.com/uzimaru0000/tv "tv Table Viewer") into a pretty table.
Currently, `abra recipe ls`, `abra server ls`, and `abra app ls` support the `-m` machine readable output flag which outputs JSON.
As you can see we, we're selecting all recipes where category is "Utilities".
#### Filter apps by state `deployed`
Note! `abra app ls -S` queries each server in your added server list, where as without the `-S` it only lists from your local copy of the sever files (thus providing no information about actual state of the apps)
Note 2! `abra app ls` lists apps grouped into a server object, with statistics about the server. In `jq` we can select the entire apps list with `.[].apps[]`.
The `del(.upgrade)` filter filters out available versions for the recipe in question for that row. It could be useful to leave in if you want a list of deployed apps that need an upgrade.
