Custom Unix Terminal

Project Overview

Developed a custom Unix terminal that can handle three internal commands - cd, echo, and pwd. The shell also supports five external commands - ls, cat, date, rm, and mkdir, each implemented using individual programs.

Internal commands are processed directly by the shell, while external commands are executed in a new process created using fork(), and the commands are run using the execl() system call. The parent process waits for the child process to terminate using wait() system calls.
