NAME

logname — display user's login name

SYNOPSIS

logname

DESCRIPTION

The logname utility writes the user's login name to standard output followed 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.
