Linux Commands Assessment Test

The correct answer is "Mkdir." This command is used to create directories in a file system. It is short for "make directory" and allows users to create new folders or directories to organize their files.

The touch command is used to create a file in a Unix-like operating system. It updates the access and modification times of an existing file or creates a new file if it doesn't exist. Therefore, touch is the correct command to create a file.

The "Is" command is used to know what files are there in the directory you are in. It lists all the files and directories present in the current directory.

The command "su" is used to switch to another user account in a Unix-like operating system. It allows a user to temporarily become another user, typically with elevated privileges. This command is often used by system administrators to perform tasks that require administrative access.

The correct answer is "Seq". Seq is a command in Unix-like operating systems that generates a sequence of numbers. By specifying the starting number (FIRST), the ending number (LAST), and the increment value (INCREMENT), the command will print the numbers in that range with the specified increment.

The command "df" displays the amount of disk space available on the file system containing each file name argument.

The command "Cmp" is used to perform byte-by-byte comparison of two files. It compares the contents of two files and displays the first mismatched byte and its corresponding line number. This command is commonly used to check if two files are identical or to find the differences between them.

Lscpu is the correct answer because it is a command that displays detailed information about the CPU architecture of the system. It provides information such as the number of processors, cores per processor, threads per core, CPU family, model, and more. This command is commonly used in Linux systems to gather CPU-related information for troubleshooting, monitoring, or system analysis purposes.

The command "df" is used to display used and available disk space.

The "Which" command is used to locate a command in the system. It helps in finding the exact location of a command by displaying the path to the executable file. This command is particularly useful when there are multiple versions or installations of a command on the system, allowing the user to specify which version they want to use.
