Task:
Write your own bash on C language.
Not use more than one global variable, think about it and be ready to explain why you do it. Show a prompt when waiting for a new command
Search and launch the right executable (based on the PATH variable or by using relative or absolute path) like in bash
It must implement the builtins like in bash:
◦ echo with option ’-n’
◦ cd with only a relative or absolute path
◦ pwd without any options
◦ export without any options
◦ unset without any options
◦ env without any options and any arguments
◦ exit without any options
; in the command should separate commands like in bash and " should work like in bash except for multiline commands
Redirections < > “>>” should work like in bash except for file descriptor aggregation
Pipes | should work like in bash except for multiline commands
Environment variables ($ followed by characters) should work like in bash
$? should work like in bash
ctrl-C, ctrl-D and ctrl-\ should have the same result as in bash
Use up and down arrows to navigate through the command using termcap (mandatory) history which we will then be able to edit (at least like we can for classic lines) if we feel like it (the line, not the history).
To run this project run in terminal:
make
./minishell
