When `dirname $0` is executed in the script, $0 is the path of the docker_build.sh script. ``` vagrant@vagrant-ubuntu-trusty-64:~$ dirname /foo/bar /foo vagrant@vagrant-ubuntu-trusty-64:~$ dirname abc . ``` - Vinod ----------------------------------------------------------- This is an automatically generated e-mail.
