Brand new user!
Hi everyone!!! 
I just want to say that I'm a new user of Unix, about 6 weeks. I'm taking a Programming and Logic course at a school in New York State, and we use Unix to operate Emacs, our code editor. I'm also taking a course called Unix Operating System. To be perfectly honest, I don't really understand everything, but I'm having fun learning!!! For my Unix class, we have to write a paper on 5 Unix resources and tell how we think they will help the average user learn about the Unix Operating System. So far, I think this is a great site because I can read about other peoples' experiences, not just commands out of a textbook. Drop me a line, I would write to you, but I dont know how!! (Yet!!!!)

geteuid
GETUID(2) Linux Programmer's Manual GETUID(2) NAME
getuid, geteuid - get user identity SYNOPSIS
#include <unistd.h> #include <sys/types.h> uid_t getuid(void); uid_t geteuid(void); DESCRIPTION
getuid() returns the real user ID of the calling process. geteuid() returns the effective user ID of the calling process. When a normal program is executed, the effective and real user ID of the process are set to the ID of the user executing the file. When a set ID program is executed the real user ID is set to the calling user and the effective user ID corresponds to the set ID bit on the file being executed. ERRORS
These functions are always successful. CONFORMING TO
POSIX.1-2001, 4.3BSD. NOTES
History In Unix V6 the getuid() call returned (euid << 8) + uid. Unix V7 introduced separate calls getuid() and geteuid(). SEE ALSO
