Yes, I did expected such an answer of using a subshell, and yes I can get the return value, but I don need it. I need the output fed into another (maybe local) variable. I was under the impression that BASH was modeled after 'C', so I started using the functions as such. My mistake. I have the conf

Bash - various feature requests

Dear All, I hope I'm posting this in the right place, since it it's really a feature request, rather than a bug report. However, here are a few things which I think would be nice to have in bash, and easy to implement: 1)substr support for a negative length argument. For example, stringZ=ab
