getlogin

This implements the C library function of the same name, which on most systems returns the current login from /etc/utmp, if any. If it returns the empty string, use getpwuid.

$login = getlogin || getpwuid($<) || "Kilroy";

Do not consider getlogin for authentication: it is not as secure as getpwuid.

Portability issues: getlogin in perlport.
