about chdir()

I just found out cd is embedded with the shell, not an actually command

I wrote the following code in my shell program, but it returns me to tell me the dir doesn't exist, what did I do wrong

Code:

char *pcd, *cd;
int i;
pcd = buf;           //buf is the shell cmd line input
if ((cd = strstr(pcd, "cd")) != NULL) {
		cd += 2;
		if ((i = chdir(cd)) !=0) {
		perror ("chdir");
		}
		exit(0);
	}

Try trimming spaces off the front of the directory name.

I got it, the problem isn't the white space, i think it is the '\n' char, it's giving a lot of troubles

From other things you've posted, it seems as if you're writing a shell, or a shell go-between - you might want to look at the strtok() function to help with things like this.
