  1. What is the standard option to provide a command line program to view its documentation?

    • -h
    • --help
    • --info
    • --doc
    • Answers Explanation & Hint:

      The standard option to provide a command line program to view its documentation is --help.

      When you run a command followed by --help, the command will display its documentation, including a brief description of the command’s functionality and the various options and arguments it supports. This is a common convention among many command-line programs to provide a quick reference for users on how to use the command effectively. It is a helpful feature for users who might be unfamiliar with the command or need a reminder of its usage.

  2. The command man​ -k is the same as the command apropos.

    True or False?

    • True
    • False
    • Answers Explanation & Hint:

      The command man -k is the same as the command apropos. Both commands are used to search the manual pages (man pages) for a specific keyword or a topic. They provide a way to find relevant commands and their descriptions based on a given keyword.

      For example, you can use either of the following commands to search for manual pages related to “network”:

      man -k network


      apropos network

      Both commands will display a list of manual pages that have the keyword “network” in their description or title. The output will include the name of the command, a brief description, and the section of the manual where the entry is found.

  3. The whatis command is the same as man -w.

    • True
    • False
    • Answers Explanation & Hint:

      The whatis command and man -w are not the same. They serve different purposes:

      whatis command: The whatis command is used to display a short one-line description of a given command or topic from the manual pages. It provides a quick summary of what the command does without displaying the entire manual page. For example, you can use whatis as follows:

      whatis ls


      ls (1) - list directory contents

      man -w command: The man -w command is used to display the path to the location of the manual page file for a given command. It is useful for finding the actual file containing the manual page without opening the full manual in the pager. For example:

      man -w ls



      The output shows the path to the ls manual page, which is located in the /usr/share/man/man1/ directory.

      In summary, whatis provides a short description of a command, while man -w gives you the path to the manual page file. They are different commands with distinct purposes.

  4. The directory where additional documentation for software packages most likely can be found is:

    • /usr/share/doc
    • /var/share/doc
    • /var/lib/doc
    • /usr/software/doc
    • Answers Explanation & Hint:

      The directory where additional documentation for software packages is most likely to be found is:


      In many Linux distributions, this is the common location where packages store their documentation files. It is a standard convention for packages to include additional documentation, such as README files, changelogs, license information, and other related materials, in this directory. The documentation files provide users with important information about the installed software and its usage.

      Please note that while /usr/share/doc is a common location, there might be exceptions, and some packages might choose to store their documentation in other locations within the file system. However, /usr/share/doc is a widely adopted location for this purpose in many Linux distributions.

  5. Which two pager commands are used by the man command to control movement within the document?

    (choose two)

    • page
    • more
    • less
    • grep
    • Answers Explanation & Hint:

      The two pager commands used by the man command to control movement within the document are:

      1. more
      2. less

      Both more and less are pager programs that allow users to view the contents of a file or document one screen at a time. They enable navigation through the document using keyboard keys such as Enter, Spacebar, arrow keys, and more. When you use the man command to view manual pages, it typically uses less as the default pager, but some systems might use more as well. These pager commands make it easier to read long documents without overwhelming the terminal with all the information at once.

  6. Commands typically executed by a user are covered in what section of the manual?

    • 2
    • 5
    • 3
    • 1
    • Answers Explanation & Hint:

      In Unix-like operating systems, the manual pages are organized into various sections to categorize different types of documentation. Section 1 is dedicated to user commands, providing information and documentation for the various commands and utilities that users can execute from the command line or terminal. When you use the man command without specifying a section, it defaults to displaying the manual page from Section 1 if available. For example:

      man ls

      This command displays the manual page for the ls command, which falls under Section 1, as it is a common user command used to list directory contents.

  7. To search the man page sections for the keyword example, which of the following command lines could you execute?

    • man -k example
    • apropos example
