Re: proposing a new package: dash (shell)

Yes, a port of dash would be welcome.

Great. I will do it.

I have done some minimal testing. dash can run its own configure script. In
order to be sure that dash.exe was the only shell use by cygwin, i copied
dash.exe over sh.exe and bash.exe.

Are you sure dash was used? Like I said, configure scripts generated by
autoconf prefer a shell that supports LINENO, and that means you might have
ended up with zsh or pdksh doing the work instead of dash. To guarantee you
used dash, you can use:

Pretty sure. I dont have pdksh installed. I have bash and ash. During my first test, i watched the task manager. I saw many sh.exe process. So i copied dash.exe over sh.exe. Second test, i saw many bash.exe process. Third time,
i replaced all shell (ash.exe, bash.exe, sh.exe, zsh.exe with dash.exe. So even if the task list show a bash.exe process, it is dash code executing. My goal was to verifiy that the code is ok. Now this does not guaranty that dash is called. In fact, even if i start the build under dash, some other shell get ran.

I would like to publish dash as is for now. If i am able to do the job, may be i can add LINENO support to dash (i have no idea what the difficulties are), or suggest to the author/actual maintainer to do it.

CONFIG_SHELL=path/to/dash path/to/dash ./configure

Ok. Will try.

I'm not ready to change the default /bin/sh; I think we'd still like to
keep /bin/sh as bash for the time being. But that doesn't stop users from
installing dash instead of bash as /bin/sh.

I am not proposing that dash become the default shell. I would like to use it on cygwin, even if it's not really POSIX compliant and there are some problems (see: ).
It is somewhat faster and is also easier to hack for a beginner and can still be useful.

And I would particularly welcome a
pre-built dash, as I already test with it as part of maintaining upstream

built on WinXP Pro, SP2, (32 bits) Do you want a copy of the dash.exe i have built ? stripped or not ? with cygwin 1.5 or 1.7 ?

I have made no modification to the original files. Just ran
to get a running dash.
