Not just with script times, but startup time will see a 2-3 fold increase as well. This can be hugely helpful with situations like using Autotools (configure), where "sh" is spawned hundreds of times. I have done heavy testing "living" with Dash. Between my repos I have over 80 Dash scripts, with usage going back to 2015: http://github.com/svnpenn/a/commit/b4908b7 I think Eric said it well: On Thu, 23 Feb 2017 14:41:52, Eric Blake wrote: > Or more likely, many people likely have pre-existing scripts wrongly > written as #!/bin/sh but which use bash-ism rather than portable > POSIX-specified shell However, I think it is worth the trouble. -- 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
