c-shell

This is a simple "shell" written purely in C. It's done as an exercise to understand the inner workings of linux shells and to get used to the C standart library.

As a start I used the codecrafters "Build your own shell" assignments.

Sample output

Things to add

• makefile
• evaluation of ENV variables
• comments (in the shell)
• update the builtin system

Valgrind

• still reachable at the end of the program is because of calling exit before freeing some resources
