User defined linux commands in a user defined shell


I am working on building a user defined linux shell using system calls and in that I have to create some user defined commands for killing all background processes, listing the processes and their statuses etc. Please tell me how to do this using system calls.

I don't have time to translate. So please help me if you know some other methods using system calls.

You waited too long to get your homework done in time.

First you have to understand how processes work, and are organized. Then you have to track what processes your "shell" creates, and how to kill them/wait for them/suspend them...

Not to mention the syntax (and all the error handling needed) for your shell in the first place.
