Simple Shell

hsh is a simple UNIX command interpreter that reads commands from standard input and executes them, simulating the behavior of the sh (/bin/sh) command interpreter (shell).
The program was written in C and is part of the low-level programming trak at Holberton School.

hsh is still under development and some functionalities contain errors, their status is indicated below.

Use

Compilation

The hsh was coded on an Ubuntu 14.04 LTS machine with gcc version 4.8.4.
The code compile with gcc -Wall -Werror -Wextra -pedantic *.c -o hsh command.

Features

In interactive mode the hsh displays a prompt (hsh> ) and wait for the user to type a command.
A command line always ends with a new line and the prompt is displayed again each time a command has been executed.

	EXAMPLE	STATUS
Handles simple commands	/bin/ls, /usr/bin/pwd	✅
Handles the PATH	ls, pwd, whoami	🔛
Handles command lines with arguments	/bin/ls -las, ls -l /tmp, cat shell.h	✅
Handles the Ctrl + D condition (end-of-file) to exit the program.		✅
Handles the Ctrl + C signal to not kill the program.		✅
Handles comments (#)	ls #-la /tmp, #pwd	✅
Handles errors.		🔛
Handles help buit-in command that prints information about builtin commands	help help, help exit	✅
Handles exit buit-in command that exits the shell	exit	🔛
Handles env buit-in command that prints the current environment	env	🔛

Examples

The shell should work like this in interactive mode:

coding-max@hbtn:~/simple_shell$ ./hsh
hsh>  ls
AUTHORS    built-ins.c  env-list.c  hsh     man_1_simple_shell  strings-1.c
README.md  dmemory.c    errors.c    main.c  shell.h             strings-2.c
hsh>  pwd
/home/coding-max/holberton/simple_shell
hsh>  exit
coding-max@hbtn:~/simple_shell$

The shell should work like this in non-interactive mode:

coding-max@hbtn:~/simple_shell$ echo "/bin/ls" | ./hsh
AUTHORS    built-ins.c  env-list.c  hsh     man_1_simple_shell  strings-1.c
README.md  dmemory.c    errors.c    main.c  shell.h             strings-2.c
coding-max@hbtn:~/simple_shell$ echo "pwd" | ./hsh
/home/coding-max/holberton/simple_shell
coding-max@hbtn:~/simple_shell$
