logname - display user's login name
SYNOPSIS
logname
DESCRIPTION
The logname utility writes the user's login name to standard output fol-
lowed by a newline.
The logname utility explicitly ignores the LOGNAME and USER environment
variables because the environment cannot be trusted.
The logname utility exits 0 on success, and >0 if an error occurs.
