It should not be there, just like it isnt' in pre-precise and cosmic+. [Test Case] * $ env -u PATH /bin/bash -c 'echo $PATH' Should not have '.' as any component. Nor should there be any empty components, i.e. '::'. [Regression Potential] * Normally PATH is always set by either init, systemd, or any other hypervisor. Thus this only affects executions under bash, when it was started without any environment - e.g. booting with 'init=/bin/bash'. [Other Info] * Original bug report. On ubuntu 16.04 (but also 14.04), running bash with PATH unset always adds '.' to PATH: philippe@pv-desktop:~$ echo $PATH /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games philippe@pv-desktop:~$ unset PATH philippe@pv-desktop:~$ /bin/bash philippe@pv-desktop:~$ echo $PATH /usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:. Even when testing in a virtual machine / docker, and erasing /root/.profile /root/.bashrc /etc/profile /etc/bash.bashrc the problem still happens.
