The distribution’s package repository is the preferred source for the installation of new applications in a Linux based operating system. A package repository is a collection of software packages that are maintained by the distribution and can be easily installed, updated, or removed using a package manager. Package repositories offer several advantages, such as:

• They ensure compatibility and stability with the system and other packages.
• They provide security updates and bug fixes for the packages.
• They reduce the risk of malware or corrupted files.
• They simplify the dependency management and configuration of the packages.

The other sources are not preferred because they may not offer these benefits and may cause problems with the system. The vendor’s version management system, the vendor’s website, or a CD-ROM disk may contain packages that are not compatible with the distribution or may conflict with other packages. A retail store may not have the latest or the most suitable packages for the system. References:

The command pwd stands for “print working directory”. It will print the absolute path of the current working directory to the terminal. For example, if we are currently in the /home/user/directory, it will print out that exact path1. The pwd command is useful for finding out where we are in the file system hierarchy and for verifying the location of files and directories2.

The other options are not commands that show the absolute path to the current working directory. The who command shows the users who are currently logged in to the system3. The cd … command changes the current working directory to the parent directory of the current one2. The ls -l command lists the files and directories in the current working directory in a long format, which shows the permissions, ownership, size, date, and name of each file and directory2. The cd ~/home command changes the current working directory to the /home directory under the user’s home directory, which may or may not exist2. References:

 The correct commands to output the content of the file Texts 2.txt are A and E. These commands use the cat command, which stands for concatenate, to display the content of one or more files. The cat command can take one or more filenames as arguments and print their content to the standard output (usually the terminal screen)12. The commands A and E use different ways to deal with the space character in the filename. The space character is a special character in Linux that separates words and commands. To prevent the shell from interpreting the space as a word separator, the commands A and E use either of the following methods34:

• Option A uses single quotes (') around the filename to preserve the literal value of the space character. This tells the shell to treat the filename as a single argument and pass it to the cat command. For example: cat ‘Texts 2.txt’
• Option E uses a backslash () before the space character to escape its special meaning. This tells the shell to ignore the space as a word separator and treat it as part of the filename. For example: cat Texts\ 2.txt

The other options are incorrect because they use different syntax that do not output the content of the file. For example:

• Option B uses a double dash (–) before the filename to indicate the end of options. This is usually used to prevent the shell from interpreting a filename that starts with a dash (-) as an option. However, in this case, the filename does not start with a dash, so the double dash is unnecessary and will cause the command to fail. For example: cat – Texts 2.txt
• Option C uses vertical bars (|) around the filename to indicate a pipe. A pipe is a way of connecting the output of one command to the input of another command. However, in this case, there is no command before or after the pipe, so the pipe is meaningless and will cause the command to fail. For example: cat |Texts 2.txt|
• Option D uses single quotes (') and a backslash () together around the filename. This is redundant and will cause the command to fail. The single quotes already preserve the literal value of the space character, so the backslash is not needed. Moreover, the backslash inside the single quotes will be treated as part of the filename, not as an escape character. For example: cat ‘Texts\ 2.txt’
