Shell script that deletes Elastic Search indices older than given amount of days
It will send a number of DELETE requests to the host specified. Will preserve indexes newer than the number of days specified on parameter.
This script will REMOVE Elastic Search indices PERMANENTLY. Use it with care and at your own risk.
The script assumes your indices are named on the following format: name-yyyy.mm.dd. E.g. my-index-2018.02.02
Run the script with the host url as the first parameter and number of days as second parameter.
