Dear ALL,

I'm C and shell beginner and I should write a sheel that does the
following:
- reads an input line from standard input, parses the line into
commands and arguments, calls the command with the arguments and waits
for it to terminate.
- includes i/o redirection, environment variables, parameter and
command substitution, command line editing and filter management.

I would greatly appreciate if anybody could provide me with a shell
that has the functionalities mentionned above and that I can start with
my learning?

Thank you very much for your ,

Beginner

I'd not start on a shell if you are knew to C.

Many shells are open-source. Take a look at bash, sh, tcsh etc. They
will all be found in Linux distros, or online online. But it is not the
sort of thing a new C programmer should be looking at.
