I would expect that giving a list with the two commands "echo yolo" and "date" would print something like > {code} > yolo > Mon Aug 26 14:40:23 PDT 2013 > {code} > Instead it prints > {code} > yolo date > {code} > This is because the commands get executed with: > {code} > exec /bin/bash -c "echo yolo date" > {code} > To get the expected behavior I have to include semicolons at the end of each command. At the very least, this should be documented, but I think better would be for the NM to insert the semicolons. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
