How to detect current locale in Mac OS X from the shell

问题

I need to detect the current locale in OS X from the command line. On Linux/Unix I can rely on LANG, but it is not always set:

I am looking for command line utilities or AppleScript code that allows me to find that information. Ideally they would work from 10.2 onwards

The closest I have found so far is

defaults read -g AppleLocale

which works on 10.3 onwards

回答1:

apropos yeilds the command locale

10.4 and later though

Edit:

defaults read .GlobalPreferences AppleLanguages | tr -d [:space:] | cut -c2-3

is mentioned here. I don't have access to a 10.2 system though, so I don't know if it works.

回答2:

locale 

or if that's not disponible

env | grep LC_

回答3:

export LANG=$(defaults read -g AppleLanguages | \
  sed '/"/!d;s/["[:space:]]//g;s/-/_/').UTF-8
