logname writes the user's login name on the standard output.
Syntax
logname |
File
/etc/profile File that is evaluated by each login shell. It is used for setting a shell environment, depending on the contents of the LOGNAME (login name of the user) environment variable passed by login. This file is created by the POSIX administrator. |
Locale
The following environment variables affect the execution of logname: LANG Provide a default value for the internationalization variables that are unset or null. If LANG is unset of null, the corresponding value from the implementation-specific default locale will be used. If any of the internationalization variables contains an invalid setting, the utility will behave as if none of the variables had been defined. LC_ALL If set to a non-empty string value, override the values of all the other internationalization variables. LC_CTYPE Determine the locale for the interpretation of sequences of bytes of text data as characters (for example, single- as opposed to multi-byte characters in arguments and input files), the classification of characters as upper- to lower-case, and the mapping of characters from one case to the other. LC_MESSAGES Determine the locale that should be used to affect the format and contents of diagnostic messages written to standard error. NLSPATH Determine the location of message catalogs for the processing of LC_MESSAGES. |
Example
You log in under the login name POSUSER1 and then display this login name.
