I&amp;#x27;ll put more effort into establishing its acceptability as a solution tomorrow.&lt;p&gt;BSDs won&amp;#x27;t have bash unless someone has gone out of their way to install it, which can be undone straightforwardly.&lt;p&gt;But it could be a long night for our Linux brethren and sistren.&lt;p&gt;Good luck, and remember to stay hydrated. :)&lt;p&gt;EDIT: obviously, don&amp;#x27;t chmod 0000 your login shell! Fix that first. Make sure whatever you switch to isn&amp;#x27;t a symbolic or hard link to bash.</text><parent_chain><item><author>cperciva</author><text>&lt;i&gt;I run no Linux&amp;#x2F;Unix&amp;#x2F;MacOS&amp;#x2F;compatible&amp;#x2F;etc machine which connects other machines&lt;/i&gt;&lt;p&gt;How about &amp;quot;I don&amp;#x27;t run bash&amp;quot;?
