Project ideas for GNU/Linux C and BASH development

Hello everyone...

I'm trying to find an interesting project to work on
for my master thesis. I like GNU/Linux C development
and BASH scripting. Please give me any idea that
flashes in your mind.

I thank you in advance...

You could write a collection of Bash loadable built-ins:

Books online: Learning the bash Shell/Appendix C. Loadable Built-Ins

I think it should be interesting convert some Unix traditional external commands into Bash internal commands and then compare the differences, possible advantages and disavantages.

Very interesting idea...

It is what I needed. However, I'm not
sure if it is enough for a master thesis.
It is important for the project to be
a bit serious and academic (master thesis).
So I think I will have to use some tools,
metrics, make some performance (but not only)
comparisons and analyses and so. And I will have
to think of an appropriate title (this cannot be changed
latter) which should be enough generic to let me add
work and extend the project and enough specific and
clear to be excepted from the department.

Definitely don't know how to thank you brother. If you
have any further suggestions please reply.

I wish you the best...

Perhaps performance improvements to the shell, or a new kind of shell.
