First, we'll call the Query Builder via cURL to get the path to the user:
curl -s -u admin:admin -X GET "http://localhost:4502/bin/querybuilder.json?path=/home/users&1_property=rep:authorizableId&1_property.value={USER_NAME}&p.limit=-1" > user.json
Next, we read the path from the JSON result:
USER_PATH=`ruby -rjson -e 'j = JSON.parse(File.read("user.json")); puts j["hits"][0]["path"]'`
Finally, the USER_PATH variable can be used to set the user's password:
curl -s -u admin:admin -Fplain={NEW_PASSWORD} -Fverify={NEW_PASSWORD} -Fold={OLD_PASSWORD} -FPath=$USER_PATH http://localhost:4502/crx/explorer/ui/setpassword.jsp
Putting it all together, if I wanted to change the admin user's password I would call:
curl -s -u admin:admin -X GET "http://localhost:4502/bin/querybuilder.json?path=/home/users&1_property=rep:authorizableId&1_property.value=admin&p.limit=-1" > user.json
USER_PATH=`ruby -rjson -e 'j = JSON.parse(File.read("user.json")); puts j["hits"][0]["path"]'`
curl -s -u admin:admin -Fplain=admin1 -Fverify=admin1 -Fold=admin -FPath=$USER_PATH http://localhost:4502/crx/explorer/ui/setpassword.jsp
I hope this would be helpful to you.
Thanks and Regards
