+title: jq
+homepage: https://stedolan.github.io/jq/
+tagline: |
+  jq is a lightweight and flexible command-line JSON processor.
+description: |
+  `jq` is like `sed` for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that `sed`, `awk`, `grep` and friends let you play with text.
+---
+
+All jq selectors begin with `.` - don't forget that!
+
+Be sure to checkout the
+[official tutorial](https://stedolan.github.io/jq/tutorial/) and
+[jq manual](https://stedolan.github.io/jq/manual/) for more info.
+
+You can also [try online](https://jqplay.org/).

+### How to select a single a property from an object
+
+```bash
+echo '{ "name": "foo" }' | jq '.name'
+```
+
+```txt
+"foo"
+```
+
+### How to remove quotes from strings
+
+The `-r` or `--raw-output` flag unwraps strings:
+
+```bash
+echo '{ "name": "foo" }' | jq -r '.name'
+```
+
+```txt
+"foo"
+```
+
+### How to select a whole object
+
+```bash
+echo '{ "name": "foo" }' | jq '.'
+```
+
+```txt
+{
+  "name": "foo"
+}
+```
+
+### How to select an element from an array
+
+```bash
+echo '[ { "name": "foo" } ]' | jq '.[0]'
+```
+
+```txt
+{
+  "name": "foo"
+}
+```
+
+### How to select a single property from an array element
+
+```bash
+echo '[ { "name": "foo" } ]' | jq -r '.[0].name'
+```
+
+```txt
+foo
+```
+
+### How to select some properties from multiple elements
+
+```bash
+echo '[ { "name": "foo" }, { "name": "bar" } ]' \
+    | jq -r '.[].name'
+```
+
+```txt
+foo
+bar
+```
+
+### How transform or zip an array
+
+Anything that doesn't start with a `.` is part of the transformation template.
+
+Anything that collects starts with `.[]`.
+
+Anything that transforms has a pipe and selector `| .whatever`.
+
+Be sure to checkout the
+[official tutorial](https://stedolan.github.io/jq/tutorial/) and
+[jq manual](https://stedolan.github.io/jq/manual/) for more info.
+
+```bash
+echo '[ { "name": "foo", "age": 0 }, { "name": "bar", "age": 2 } ]' \
+    | jq '{ names: [.[] | .name], ages: [.[] | .age] }'
+```
+
+```txt
+{
+  "names": [
+    "foo",
+    "bar"
+  ],
+  "ages": [
+    0,
+    2
+  ]
+}
+```
