Removing more than 1 Nomad job at a time

Sometimes when you’re hacking around (possibly with Hashicorp Waypoint) you will find yourself with a large number of dead jobs. Here’s a small snippet to clean those jobs up. This relies on pattern matching, so in this particular example the script would clean up:

Input

example-nodejs-01emsh754y7q217j536dk1bnp8
example-nodejs-01emshatc21ns5apgf9zfycfcw
example-nodejs-01emshfvg26rxn8km4amzn6dzf
example-nodejs-01emshjxs6639raf8kftmzqsby
example-nodejs-01emshmtvbd0xn4m0hjae9gafq
example-nodejs-01emshzq9ksn378f9z10t52bj9
example-nodejs-01emsj176yyjj3vpth2h2dgra7
example-nodejs-01emsj1ts3j9qpmdrtb1byd45p

Solution

$JOB_NAME=example-nodejs
nomad status | grep $JOB_NAME | awk '{print $1}' | xargs -n1 -I{}  nomad stop -purge {}
