Check Jenkins for build status via a shell script

This can be handy for embedding into a tmux status bar, occasional checks in a terminal or embedding as part of another process. Saves you having to go to the Jenkins web page.

The following script can also be found as a gist here.

Use like this: 'checkJenkins.sh <jobname>' and it will query the server with the given job name every 30s. Use like this: 'checkJenkins.sh <jobname> tmux' and it will query the server once and output tmux coloured messages appropriate to display in a tmux status bar. E.g. add this to your .tmux.conf 'set -g status-right "#(checkJenkins.sh jobname tmux)"

#!/bin/bash
