Simple command line interpreter in C

I need you to write a simple command line interpreter that can interpret a set of internally implemented commands. I would like this software to be developed for Linux using C or C++.  The interpretor should be able to do the following:- Accept user commands from the command line- Show a specific prompt (like '$>') to indicate that it is prepared to receive user command.- Execute user commands from a list of accepted commands- Consider the following error sitations:       - Command execution returned an error      - The issued command is not an accepted command      - Arguments are in the wrong formatAccepted commands:1. The 'tail' command with parameters -c, -n, -q, -v2. The 'uniq' command with parameters -i, -d, -u3. The 'cd' command (no params)4. Support for pipes in the commands (eg > ls -l | grep -e 'tmp' | wc -l)
