Question

I’m using lighttpd and wrote the following cgi script:

main(){
    printf("Content-type: text/html\n\n");
    char * pwd ="";
    pwd=getenv("PWD");
    printf ("The current path is: %s",pwd);
}

The Result is

The current path is: (null)

Well, I don’t get why. And I don’t know how to find the path of the script executed. I’m looking for args[0] with a path, and used pwd for that, but maybe I should switch to something different.

UPDATE

Not working aswell is

char cwd[_PC_PATH_MAX+1];
getcwd(cwd, _PC_PATH_MAX+1);

cwd is ” “. Maybe my script knew where it was if I stoped using room 1408 as my datacenter. 😛

Answer 1

Use getcwd() instead. PWD isn’t required to be set.

#include <unistd.h>

char *getcwd(char *buf, size_t size);
