(I'm new to Linux and to Ubuntu) In Settings I can choose a "locale" which then determines how dates, numbers etc. are formatted. But there is no locale corresponding to what I need, and I have found no simple ways of setting formats independently of a locale pack. What I would like is all applications to use:
language = English UK
keyboard = Swiss French
date = YYYY-MM-DD (e.g. 2020-12-25)
time = HH:MM:SS (e.g. 17:45:03)
currency = €
units = metric
number thousands separator = "'" and decimal = "." (e.g. 12'345'678.99 )
first day of the week = Monday
This should be easy. What am I missing? All the answers possibly related to this that I have found do not address a complete or easy solution. I.e. there seems no simple way to set the formats independently of each other.
LC_*
environment variables. Seeenv | grep -E '^LC_'
andman locale
.man locale
contains examples of how to customize your locale settings.
