into the system.
NOTES
The logname command explicitly ignores the LOGNAME environment variable
to avoid erroneous results from environment changes.
EXIT STATUS
The following exit values are returned: Successful completion. The
getlogin() utility would fail.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of *cmd*: Pro‐
vides a default value for the internationalization variables that are
unset or null. If LANG is unset or null, the corresponding value from
the default locale is used. If any of the internationalization vari‐
ables contain an invalid setting, the utility behaves as if none of the
variables had been defined. If set to a non-empty string value, over‐
rides the values of all the other internationalization variables.
Determines the locale for the interpretation of sequences of bytes of
text data as characters (for example, single-byte as opposed to multi‐
byte characters in arguments). Determines the locale for the format
and contents of diagnostic messages written to standard error. Deter‐
mines the location of message catalogues for the processing of LC_MES‐
SAGES.
