Hi there,
After reading your project description it looks like you require a Unix shell implementation in C to be completed. Specifically, you require a history feature to be implemented. This history feature must store the 10 most recent commands entered with the associated number indicating its ordering.
I have over 5 years of experience in creating C solutions so this project would be no problem for me. I have also completed similar Unix shell projects in C. I could complete it in under a day.
Regards,
John
