description |
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. |
[Impact]
* The fallback path built into bash contains '.' which leads to unexpected addition of the current working directory. 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. |
