The locale settings in Linux methods assist make sure that info like dates and occasions are displayed in a format that is smart within the context of the place you reside and what language you converse. Here is use them.
NOTE: Not one of the instructions described on this submit will change your locale settings. Some merely use a unique locale setting to show the response you is perhaps seeing from a unique location.
Listing your settings
If you happen to’re within the US, it is best to see one thing like this if you use the locale command to checklist your settings:
$ locale LANG=en_US.UTF-8 LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL=
The en_US.UTF-8 settings within the above output all characterize US English. If you happen to’re in France, this response is extra probably:
LANG=fr_FR.utf-8 LC_CTYPE="fr_FR.utf8" LC_NUMERIC="fr_FR.utf8" LC_TIME="fr_FR.utf8" LC_COLLATE="fr_FR.utf8" LC_MONETARY="fr_FR.utf8" LC_MESSAGES="fr_FR.utf8" LC_PAPER="fr_FR.utf8" LC_NAME="fr_FR.utf8" LC_ADDRESS="fr_FR.utf8" LC_TELEPHONE="fr_FR.utf8" LC_MEASUREMENT="fr_FR.utf8" LC_IDENTIFICATION="fr_FR.utf8" LC_ALL=fr_FR.utf8
A whole bunch of traces of output will likely be displayed in the event you use the locale -a (checklist all locales) command because it lists locales from across the globe.
$ locale -a | wc -l 869
Right here’s a pattern:
$ locale -a | column | head -10 aa_DJ es_CO.iso88591 ms_MY.utf8 aa_DJ.iso88591 es_CO.utf8 mt_MT aa_DJ.utf8 es_CR mt_MT.iso88593 aa_ER es_CR.iso88591 mt_MT.utf8 aa_ER@saaho es_CR.utf8 my_MM aa_ER.utf8 es_CU my_MM.utf8 aa_ER.utf8@saaho es_CU.utf8 nan_TW aa_ET es_DO nan_TW@latin aa_ET.utf8 es_DO.iso88591 nan_TW.utf8 af_ZA es_DO.utf8 nan_TW.utf8@latin
Just like the en_US settings proven above, these codes, stand for the language and county (e.g., aa_DJ stands for Afar, Djibouti). You’ll be able to show an entire checklist with a command like the next that selects the parts on traces previous to the durations and limits the output to one among every earlier than organizing the itemizing in columns:
$ locale -a | grep "." | awk -F. '{print $1}' | uniq | column

Discover that solely 4 of the codes don’t use two-part naming: “C” for the POSIX standards-compliant format, “eo” for “esperanto” (the world’s most generally spoken constructed worldwide auxiliary language), Japanese and Korean .
Viewing and looping via months and days
I found not too long ago that I the locale command can show the months of the yr or the times of the week with instructions like these:
$ locale mon January;February;March;April;Could;June;July;August;September;October;November;December $ locale day Sunday;Monday;Tuesday;Wednesday;Thursday;Friday;Saturday
The above instructions make looping via the months of the yr or the times of the week surprisingly simple. For instance, to loop via the months, use a command like this:
$ months=`locale mon | sed 's/;/ /g'` <== flip semicolons into blanks $ for mo in $months > do > echo $mo > achieved January February March April Could June July August September October November December
To loop via the times of the week, do that:
$ weekdays=`locale day | sed 's/;/ /g'` $ for day in $weekdays > do > echo $day > achieved Sunday Monday Tuesday Wednesday Thursday Friday Saturday
Change the lauguage used for months and days
You may as well use a locale setting to show the months of the yr or the times of the week in another language. For instance, to show the months in French, use a command like this one:
$ LC_ALL=fr_FR.utf8 locale mon janvier;février;mars;avril;mai;juin;juillet;août;septembre;octobre;novembre;décembre
To see the months in Swahili as an alternative, do that:
$ LC_ALL=sw_TZ.utf8 locale mon Januari;Februari;Machi;Aprili;Mei;Juni;Julai;Agosti;Septemba;Oktoba;Novemba;Desemba
To checklist the present date and time in Russian and Italian, use instructions like these:
$ LC_ALL=os_RU.utf8 date
Крс 02 Янв 2023 11:35:31 EST $ LC_ALL=it_IT.utf8 date dom 3 gen 2023, 16:29:10, EST
Wrap-Up
Your locale settings are in place to make sure that date, time, and associated particulars are displayed within the format that is smart to you. They will, as described on this submit, additionally permit you to generate month-of-year and day-of-week loops and to show date/time info in different languages.
