This variable says which user's init files should be used by Emacs—or
""stands for the user who originally logged in. The value reflects command-line options such as ‘-q’ or ‘-u user’.
Lisp packages that load files of customizations, or any other sort of user profile, should obey this variable in deciding where to find it. They should load the profile of the user name found in this variable. If
nil, meaning that the ‘-q’ option was used, then Lisp packages should not load any customization files or user profile.
This holds the nominal email address of the user who is using Emacs. Emacs normally sets this variable to a default value after reading your init files, but not if you have already set it. So you can set the variable to some other value in your init file if you do not want to use the default value.
This function returns the name under which the user is logged in. It uses the environment variables LOGNAME or USER if either is set. Otherwise, the value is based on the effective UID, not the real UID.
If you specify uid (a number), the result is the user name that corresponds to uid, or
nilif there is no such user.
This function returns the user name corresponding to Emacs's real UID. This ignores the effective UID, and the environment variables LOGNAME and USER.
This function returns the full name of the logged-in user—or the value of the environment variable NAME, if that is set.
If the Emacs process's user-id does not correspond to any known user (and provided
NAMEis not set), the result is
If uid is non-
nil, then it should be a number (a user-id) or a string (a login name). Then
user-full-namereturns the full name corresponding to that user-id or login name. If you specify a user-id or login name that isn't defined, it returns
user-full-name are variables as well as functions. The functions
return the same values that the variables hold. These variables allow
you to “fake out” Emacs by telling the functions what to return. The
variables are also useful for constructing frame titles (see Frame Titles).
This function returns the real UID of the user. The value may be a floating point number, in the (unlikely) event that the UID is too large to fit in a Lisp integer.
This function returns the effective UID of the user. The value may be a floating point number.
This function returns a list of strings, listing the user names on the system. If Emacs cannot retrieve this information, the return value is a list containing just the value of
