Hello, I'm wondering why we are using bash as a shell interpreter. It's licenced under the GPL, and we're trying to be an MIT-Licenced system. Also, it's big and complicated. We apparently have a set of hacks which prevent us to use the mainstream version and force us to have it in our source. I would like to switch to mksh . This one compiles out of the box on Haiku. The sourcecode is a lot simpler, and it doesn't feature all the annoying utf-8 bugs that end up making your command line all borked. The binary is also about 4 times smaller for equivalent functionality. I did some tests and replaced bash in my Haiku install with mksh. The bootscript needed one change to the launch function, as mksh doesn't like "shift" when there is only one argument. I'm not sure this is a bug in mksh or a real difference between it and bash, as mksh aims for korn shell compatibility. This would be a move away from BeOS, but bash could still be provided as an optional package for people really needing it (and I don't think there is much BeOS software relying on bash being there). Finally, this would allow us to close a lot of coverity bugs. Any good reason not to make the switch ?  https://www.mirbsd.org/mksh.htm -- Adrien.
