Nice strawman argument. You seem to assume that Dash implements nothing beyond POSIX (and hence anything that runs on dash must run on every other shell). This is not the case.
Perhaps you should have read my full post. Here, let me quote myself and link for you: On Sat, 25 Feb 2017 09:08:55, Steven Penny wrote:

http://cygwin.com/ml/cygwin/2017-02/msg00320.html So, as I said before and now again, Dash is a minimal shell, similar to POSIX shell. Yes, it is possible to be in a situation like this: - script has #!/bin/sh - script has Dashisms, which can cause problem on POSIX shell However being that "echo -n" and "local" are probably the only Dashisms, that is trivial to fix. Compare to a Bash problem: - script has #!/bin/sh - script has Bashisms, which can cause problem on POSIX shell Even switching from a Bash script to Dash script can be a herculean task, if the script heavily relies on Bashisms like arrays, herestrings, process substitution, etc. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
