logname - return user's login name

logname

The logname utility writes the user's login name to standard output. The login name is the string that would be returned by the getlogin(3C) function. If getlogin() does not return successfully, the name corresponding to the real user ID of the calling process is used instead. If a name cannot be found, the user's ID will be printed.

See environ(7) for descriptions of the following environment variables that affect the execution of logname: LANG, LC_ALL, LC_CTYPE, LC_MESSAGES, and NLSPATH.
