Own Shell: Displaying prompt and write a command

Hi,

I'm building my own shell, I've search on the forums but I couldn't find this anywhere.

I have something like this:

Code:

---

void showPrompt(){
  char buff[200];
  getcwd(buff, sizeof(buff));
  printf("%s:> ", buff);
}

.
.
.

---

And on the main function:

Code:

---

.
.
.
do{
  showPrompt();
  if(strcmp(argv[0], "Pwd") == 0){
    printf("%s\n", Pwd() );
  }

  if(strcmp(argv[0], "Exit") == 0){
    exit(1);
  }
}while(Exit != 1);

---

what happens when I run the program is that every char, word, number and even any command I write, it gives me the current location.

I assume that my showPrompt function is very badly done and the program is showing me the getcwd/pwd all the time?

Could anyone help me out making a good showPrompt function?


Thanks in advance!

In this case

Code:

---

void showPrompt(){
  char buff[200];
  printf("%s:> ", buff);
}

---

buff is not initialized.

Sorry, I forgot to insert a line while copying the code. I fixed it above.

Any ideas?

Why wouldn't it give you the current location? It's part of your prompt that you keep displaying in a loop.


Quzah.

Making some tests with a variable "command" instead of using argv, I made it work with the command "Exit"

if I now enter let's say "a", it won't give me the current location like before.

I think I have a good showPrompt after all..
