• getlogin

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

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

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

  Portability issues: getlogin in perlport.
