# Kill processes orphaned by Jenkins

# Work around Java's use of SIGTERM rather than SIGKILL and
# Jenkins's lack of any workaroud in the box.

# Suggested usage:
#
#     $ crontab -l
#     */5 0 0 0 0 /path/to/kill-processes-orphaned-by-jenkins.sh 2>&1 | logger 

# Tested on Mac OS X (BSD). Probably needs `ps` arguments
# ported for Linux (GNU).

for url in $(ps -wwEf | grep BUILD_URL | grep -v ' grep' | tr ' ' '\n' | grep BUILD_URL | sort | uniq | awk -F'=' '{ print $2 }')
do
    # Get your API token from
    # http://<jenkins-host>/user/<user>/configure > Show API
    # Token...
    curl -s -u '<user>:<token>' "$url"'/api/json?tree=building' | grep -q true
    building=$?
    false=1
    if [ $building -eq $false ]
    then
        for pid in $(ps -wwEf | grep "$url" | grep -v ' grep' | awk '{ print $2 }')
        do
            echo 'Finished job: '"$url"
            echo 'Killing process orphaned by Jenkins:'
            ps -f -p $pid
            echo
            kill -9 $pid
        done
    fi
done

neat tool. I forked it to work on linux (and add a couple other options)
