<html><body><div>Hi Greg,</div><div><br data-mce-bogus="1"></div><div>First solutions that come to my mind are to maybe create a shell script for the whole command sequence (lazier) or, Buildbot supports setting environment variables for specific commands with env, like here: <a href="http://docs.buildbot.net/latest/manual/cfg-buildsteps.html#using-shellcommands">http://docs.buildbot.net/latest/manual/cfg-buildsteps.html#using-shellcommands</a></div><div><br data-mce-bogus="1"></div><div>Hope this helps,</div><div>Gabe</div><div><br>On Jul 26, 2018, at 09:46 PM, Greg Bullock <greg@nwra.com> wrote:<br><br></div><div><blockquote type="cite"><div class="msg-quote" text="#000000" bgcolor="#FFFFFF">I'm using Buildbot version: 1.3.0.
