Re: [Bashdb-help] bashdb syntax error with for loop

[Rocky B. <roc...@gm...>]

Ok. I think I have found and fixed the problem. Thanks for whittling it down
to something manageable.

(It was something really silly; surprising it wasn't detected earlier.)
Please try out what's in git on sourceforge or the candidate release tarball
http://bashdb.sourceforge.net/bashdb-4.0-0.4git.tar.bz2

There will probably be a general release soon.

Thanks
