# 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 (‘`\n`’).

The `logname` utility explicitly ignores the `LOGNAME` and `USER` environment variables because the environment cannot be trusted.

# EXIT STATUS

The `logname` utility exits 0 on success, and >0 if an error occurs.

# SEE ALSO

who(1), whoami(1), getlogin(2)

# STANDARDS

The `logname` utility is compliant with the IEEE Std 1003.1-2008 (“POSIX.1”) specification.

# HISTORY

The `logname` command first appeared in PWB/UNIX 1.0 and was reimplemented for 4.3BSD-Net/2.
