I had a bunch of compressed json files that I needed to pretty print to make them more readable. This little snippet will create a new pretty printed json file prefixed with pp:
ls *.json | xargs -I {} sh -c "cat {} | python -mjson.tool > pp{}"
Instead of having to look at files that look like this:
{ "attributes": [ { "name": "type", "value": "PKT" }, { "name": "arch", "value": "x86_64,x86" }, { "name": "name", "value": "Awesome OS" } ], "dependentProductIds": [], "href": "/products/00", "id": "00", "multiplier": 1, "name": "Awesome OS", "productContent": [ { "content": { "arches": null, "contentUrl": "/content/6/$releasever/$basearch/debug", "gpgUrl": "file:///etc/pki/rpm-gpg/RPM-GPG-KEY-awesome-os", "id": "FFFF", "label": "awesome-os-debug-rpms", "metadataExpire": 86400, "modifiedProductIds": [ "0A" ], "name": "Awesome OS (Debug RPMs)", "releaseVer": null, "requiredTags": "awesome-os-server", "type": "yum", "vendor": "Candlepin" }, "enabled": false } ] }
You get a bunch of files that look like this:
{ "attributes": [ { "name": "type", "value": "PKT" }, { "name": "arch", "value": "x86_64,x86" }, { "name": "name", "value": "Awesome OS" } ], "dependentProductIds": [], "href": "/products/00", "id": "00", "multiplier": 1, "name": "Awesome OS", "productContent": [ { "content": { "arches": null, "contentUrl": "/content/6/$releasever/$basearch/debug", "gpgUrl": "file:///etc/pki/rpm-gpg/RPM-GPG-KEY-awesome-os", "id": "FFFF", "label": "awesome-os-debug-rpms", "metadataExpire": 86400, "modifiedProductIds": [ "0A" ], "name": "Awesome OS (Debug RPMs)", "releaseVer": null, "requiredTags": "awesome-os-server", "type": "yum", "vendor": "Candlepin" }, "enabled": false } ] }
JQ is a cool command line json parser that does the same thing: https://stedolan.github.io/jq/
cat test.json | jq .
I recommend it if you use a lot of JSON stuff.
What about jq?
