Linux Lupina - Terminal

The correct answer is "umount." This command is used to safely remove or unmount a USB key or any other mounted device from the system. By using the "umount" command, the operating system ensures that all data has been written to the device and any ongoing processes are completed before allowing the device to be safely removed. This helps prevent data corruption or loss that could occur if the device is removed without proper unmounting.

The command "find *.txt" is used to search for all text files in the directory "/home/ubunto/Documents/domace_naloge/1_naloga". The command "find" is used to search for files and directories based on specified criteria, in this case, the criteria is files with the extension ".txt". The asterisk (*) is a wildcard character that represents any characters before the ".txt" extension.

The given answer suggests that the command "chmod 644 domaca_1.txt" should be used to protect the file "domaca_1.txt" in a way that the owner can read and write, while others can only read. The "chmod" command is used to change the permissions of a file or directory, and the numbers "644" represent the permission settings. The first digit "6" represents the owner's permissions, which include read and write access. The second and third digits "4" represent the group and others' permissions, which only include read access.

The correct answer suggests that the first command should be "cd Documents" to navigate to the Documents directory. Then, the "ls" command is used to list the contents of the Documents directory. Finally, the "mkdir domace_naloge" command is used to create a new directory called "domace_naloge" within the Documents directory.

The correct answer is "cat > domaca_1.txt". This command creates a file named "domaca_1.txt" and redirects the output of the "cat" command (which is the text "To je moja prva domača naloga") into the file. This will result in the desired file "domaca_1.txt" with the specified text inside it.

The correct answer is "cp domaca_1.txt domaca_2.txt". This is the correct command to copy the file "domaca_1.txt" and rename it as "domaca_2.txt" within the same directory. The "cp" command is used to copy files, and by specifying the source file "domaca_1.txt" and the destination file "domaca_2.txt", the file is copied and renamed accordingly.

The correct answer is "rm -r 2_domaca". This command is used to remove a directory and its contents recursively. In this case, we want to delete the directory "2_domaca" and all its files and subdirectories within it. The "rm" command alone would only delete files, but not directories. The "-r" option is necessary to remove directories recursively.
