How to localize a script in BASH?

Question

bash

Good day! Sobsno wondered about the localization of the BASH script... The language files are in a certain folder. Their content is of the form: language=Russian. Their names correspond to the code names of the languages ​​(ru.lng, en.lng, etc.). Their content is read and displayed. The problem is that I can not think of any way to display a menu for their selection. That is, a person has created his own language file (for example, uk.lng), in each of these files there is a line language=LanguageName. How can I list these languages ​​in the menu based on the files in their language directory (the name of the language from the language file will get: language=).
I know it's a stupid question, don't kick too much. Who cares, could you provide an example of such an implementation? Thanks in advance.

Answer 1

#!/bin/bash

declare -A LANGUAGES

BASE="./langs"
for path in $(find $BASE -name '*.lng')
do
        base=$(basename $path)
        language=${base%.*}
        line=$(grep "language" $path)
        name=${line#*=}
        LANGUAGES[$name]=$language
done

echo ${!LANGUAGES[@]}
echo ${LANGUAGES[@]}

select l in ${!LANGUAGES[@]}
do
        echo "Selected: $l"
        echo "Selected file: " $BASE/${LANGUAGES[$l]}.lng
        break
done
