What is the output of this program?

[t048]

I'm running this program, but I don't see any output. What do you get?

#include <stdio.h>
#include <pwd.h>
#include <unistd.h>

int main (){


struct passwd *p  = getpwuid (getuid());
printf ("(%s)\n", p->pw_gecos);
return 0;
}

# g++ test.cpp
test.cpp:11:2: warning: no newline at end of file
# ./a.out
()
#

There is no output. When I looked in pwd.h, it says the gecos field is the user's name. I guess I don't have a name

Well fix that!

gorn:x:500:500:GoRN ToTheRescue:/home/gorn:/bin/bash

the user's name is GoRN ToTheRescue, just put something in that field and you'll have a gecos.

OK, thanks. Where is this field?

in /etc/passwd
