<li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Bash doesn’t happily let me embed double quotes inside a subshell inside a subshell inside double-quotes. All of the double-quotes are required, AFAICT. So doing X=$(…”$(…”xxx”)”)
just doesn’t work because bash doesn’t parse nested double-quotes. But both the inner var and the result can and will have spaces in them.<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">I can’t remember how in shell (bash, in this case) how to bifurcate stdout and have it run to two pipelines. I figure echo is a builtin, so should at least be lighter than re-running
the monstrosity that is openssl over and over. I have a vague recollection that this is harder than it sounds, and may not be worth it…<o:p></o:p></li></ol>

<p class="MsoNormal">Any suggestions on how to solve either issue? I’m sure I’ve just forgotten some obvious technique, hopefully someone can jog my mind.<o:p></o:p></p>
