attacking the problem

Begin your solution by reading the UNIX example in Section $2\mathrm{.}4.$ You will have to rewrite

that code to support user interaction. Here is a header file, minishe $11.h,$ for your mini$-$

shell:

Here is the skeleton of a solution:

$1**$

This is a very minimal shell. It finds an executable in the

PATH, then loads it and executes it $($using execv$).$ Since

It uses N$.$N $($dot$)$ as a soparator, it cannot handle file

names like $"$

minishell.hN

The focus on this exercise is to use fork, PMTH variables,

The focus on this exercise is to use fork, PAPH variables,

the end of Chapter $9.$
