Codeur mbash - C Programming Bash

Example

chdir("/path/to/directory");

Scenario

When a user inputs 'cd /path/to/directory', mbash processes this input to change the current working directory using the chdir system call, updating the environment accordingly.

Example

char cwd[1024]; getcwd(cwd, sizeof(cwd)); printf("%s\n", cwd);

Scenario

For the 'pwd' command, mbash fetches the current directory path using getcwd and displays it, providing users with their current directory context.

Example

execvp("ls", argv);

Scenario

mbash interprets user commands like 'ls' by searching for the executable in directories listed in the PATH variable and executing it with execvp, handling both built-in and external commands seamlessly.

Example

if (fork() == 0) { execvp("sleep", argv); }

Scenario

When a command ends with '&', mbash initiates the command as a background process, allowing the terminal to accept new commands while the previous command runs concurrently.
