LOGNAME(1)

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.
