I'm running Emacs on a linux system and the function user-full-name, when called with no arguments, always returns an empty string.

How can I fix this?

I assume it's something I need to configure on my user account, maybe an environment variable.

(The variable user-login-name works fine.)

The function user-full-name with no arguments returns the value of the variable user-full-name. This variable is initialised:

  • to the value of the environment variable NAME if it is defined; or
  • to the Gecos field of the passwd entry.

Therefore, you can do one of the following:

  • set the Gecos field of your passwd entry using one of the chfn or usermod commands;
  • set your user name in the NAME environment variable in your shell's initialisation file;
  • set the user-full-name variable in your Emacs' initialisation file.

Google is your friend. =/

$ chfn -f "Full Name"
