> To avoid any confusion: Solaris 11 is a platform [not supported officially|http://lists.digium.com/pipermail/asterisk-dev/2018-January/076770.html] but relies on contributions from the community. This patch here is part of a series to get Asterisk going on the latest Oracle Solaris. Or stated differently: Much more must be done, to get Asterisk working there. Let us tackle this one after another.
> This issues was caused by Commit [29304d1|http://github.com/asterisk/asterisk/commit/29304d10a0981fddf020b0c8655d041d3f15960f#diff-67e997bcfdac55191033d57a16d1408a] (ASTERISK-20850). The problem is the use of double-quotes within backticks within double-quotes. Some shell parsers like the one of Solaris 11, do not match the backticks but stop on double-quote. The parser thinks the quote ended after {{`echo}}. The rest is then executed on the shell, which creates chaos.
> On the Stack Exchange network, a lot of discussions exists how to tackle this: [387246|http://unix.stackexchange.com/q/387246]. My approach are single-quotes as inner quotes because their content is needed literally. As a side-effect that helps the parser not to end the initial quote. That approach is taken in the attached patch.
> Normally, single-quotes within double-quotes [lose their meaning|http://unix.stackexchange.com/a/169512]. However, the single-quotes are within backticks and evaluated as 'usual'. Other approaches would have been:
> * replace backticks with {{$(...)}} and/or
> * replace the double-quotes with test -n or test -z.
