chdir() - no such file or directory

Question

``` int main(int argc, char **argv) { char input[150]; char change[2] = "cd"; char *directory; while(1) { prompt(); fgets(input, 150, stdin); if(strncmp(change, input, 2) == 0) { directory = strtok(input, " "); directory = strtok(NULL, " "); printf(directory); chdir(directory); perror(directory); } if(feof(stdin) != 0 || input == NULL) { printf("Auf Bald!
"); exit(3); } } } ``` when i start this and type in "cd test" i get "no such file or directory". But there is the directory "test". Runs on Arch Linux.

Accepted Answer

From the man page:

fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an EOF or a newline. If a newline is read, it is stored into the buffer.

The problem is there's a newline character `'
'` at the end of your string that you got from `fgets()`, you need to remove it:

```
fgets(input, 150, stdin);
input[strlen(input)-1] = '\0';
```

Also:

```
char change[2] = "cd";
```

That should be `change[3]`, it's 2 (for "cd") + 1 for the NULL terminator `'\0'` which is automatically placed for you.

Then it should work.

EDIT:

A different alternative is to change the `strtok()` call such that:

```
directory = strtok(NULL, " 
");
```

This will work if the user enters the string via the enter key or via the EOF (ctrl + d on Linux) character... I'm not sure how likely the second is for a user to do... but it couldn't hurt!
