Guys, There are many shell/python script files in cloudstack which contain grep or sed commands (which may return greedy results) . Some issues are because of these files, for instance CLOUDSTACK-3540, CLOUDSTACK-3533, CLOUDSATCK-3843.
We need to check all the script files in patches/ and scripts/ directory, and fix the potential issues.
