The existence of shells is linked to the very existence of IT. At the time, all developers agreed that communicating with a computer using aligned 1/0 switches was seriously irritating. It was only logical that they came up with the idea of creating a software to communicate with a computer using interactive lines of commands in a language somewhat close to the human language. Thanks to Minishell, you’ll be able to travel through time and come back to problems people faced when Windows didn’t exist.
Using make will create the minishell executable.
Simply run it with :
./minishell
Minishell runs executables from an absolute, relative or environment PATH (/bin/ls or ls), including arguments or options. ' and " work the same as bash, except for multiline commands.
You can separate commands with ;, as well as use redirections > >> < and pipes |.
Environment variables are handled, like $HOME, including the return code $?.
Finally, you can use Ctrl-C to interrupt and Ctrl-\ to quit a program, as well as Ctrl-D to throw an EOF, same as in bash.
A few of the functions are "built-in", meaning we don't call the executable, we re-coded them directly. It's the case for echo, pwd, cd, env, export, unset and exit.
