I prefer == for [[ too, but no difference. = is required for [ by POSIX but |
| 9 |
Bash allows either (bad though). The real issue is executing two commands |
| 10 |
since [[ can short-circuit and works as you expect. Two are only needed with [ |
| 11 |
because -a and -o are so unpredictable. |

[[ $x == en || $x == en-US ]] |
| 14 |
or |
| 15 |
case $x in en|en-US) ...;; esac; |
| 16 |
or |
| 17 |
[[ $x == @(en|en-US) ]] |
| 18 |
or |
| 19 |
[[ $x == en?(-US) ]] |
