petulia3478

$ localectl
   System Locale: LANG=en_US.UTF-8
       VC Keymap: us
      X11 Layout: us

To list available locales

$ localectl list-locales

To set a locale

$ localectl set-locale <locale>

This makes a system-wide change, To set the locale to American English do the following. The change does not take effect after next login, not a new terminal session. It is actually editing the /etc/locale.conf file.

$ sudo localectl set-locale LC_TIME="en_US.UTF-8"

To see differences in locale settings before you change settings, you can run something like this, for instance if changing the LC_TIME setting.

$ LC_TIME=en_US.UTF-8 date
Mon Jan 28 07:51:58 GMT 2019

and American English.

$ LC_TIME=en_GB.UTF-8 date
Mon 28 Jan 07:52:04 GMT 2019
