Portuguese (pt)?
Click on the arrows to vote for the correct answer
A. B. C. D. E.D
The correct command to add to /etc/bash_profile in order to change the language of messages for an internationalized program to Portuguese (pt) is:
D. export LC_MESSAGES="pt"
Explanation:
When an internationalized program is executed, it looks for a set of environment variables to determine which language should be used for its messages. One of these variables is LC_MESSAGES.
The LC_MESSAGES environment variable specifies the language to be used for message translations. Its value should be a valid locale identifier, which consists of a language code (pt in this case) and an optional country code or other modifiers.
Therefore, in order to set the LC_MESSAGES environment variable to Portuguese (pt), the correct command to add to /etc/bash_profile is:
export LC_MESSAGES="pt"
Option A is incorrect because the LANGUAGE environment variable is used to set the language preferences for user interfaces and other text-based applications, not specifically for message translations.
Option B is incorrect because there is no MESSAGE environment variable used to set the language for message translations.
Option C is incorrect because the UI_MESSAGES environment variable is not a standard environment variable used to set the language for message translations.
Option E is incorrect because there is no ALL_MESSAGES environment variable used to set the language for message translations.
