Question No. 2

Which of the following commands should be added to /etc/bash_profile in order to change the language of messages for an internationalized program to Portuguese (pt)?

Show Answer Hide Answer
Correct Answer: D

The LC_MESSAGES environment variable specifies the language to use in diagnostic messages for an internationalized program. It can be set to any value supported by the installation, such as pt for Portuguese, en for English, fr for French, etc. The LC_MESSAGES variable can be set either globally in a shell profile file, such as /etc/bash_profile, or locally in a shell session. For example, to set the language of messages to Portuguese for the current shell session, one can use the following command:

export LC_MESSAGES=pt

To verify the change, one can run an internationalized program, such as man, and see the output in Portuguese. The LC_MESSAGES variable can also be used to run a single command with a different language without affecting the system's language. For example, to run the man command with the Spanish language, one can use the following syntax:

LC_MESSAGES=es man

The LC_MESSAGES variable is useful for testing how programs behave in different languages or for displaying messages in different languages1234.Reference:

Question No. 5

What is true regarding the file ~/.forward?

Show Answer Hide Answer
Correct Answer: D

The file ~/.forward is a text file that contains one or more email addresses to which the incoming mail for the user will be forwarded123.The file is owned by the user and can be edited with any text editor123.The file does not require any special syntax or commands, just a list of email addresses separated by commas or newlines123. For example, if the user wants to forward their mail to alice@example.com and bob@example.com, they can create a ~/.forward file with the following content:

alice@example.com, bob@example.com

The MTA will read the ~/.forward file and send a copy of each incoming mail to the specified addresses123. Therefore, the correct answer is D. When configured correctly, ~/.forward can be used to forward each incoming mail to more than one other recipient.

The other options are false regarding the file ~/.forward.The file is not owned by the MTA and does not need to be edited with the editaliases command, which is used to edit the system-wide aliases file, not the user-specific ~/.forward file4.The user does not need to run newaliases to make the MTA aware of the changes, as the MTA will check the ~/.forward file every time a mail is delivered to the user123.The newaliases command is used to rebuild the system-wide aliases database, not the user-specific ~/.forward file4.The file ~/.forward does not have any restrictions on the email addresses that can be used for forwarding, as long as they are valid and reachable123. The root user can also use the ~/.forward file to forward their mail, but it is not recommended for security reasons.
