Primary Response: Within the Discussion Board area, write 200 word that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas.
For this Discussion Board, please complete the following:
Like the Windows operating system, Linux also provides keyboard shortcuts for most commands, allowing users to simply press two or more keys on the keyboard at same time instead of typing the exact spelling of the original word to issue a command. These shortcuts are a very convenient and fast way to perform various Linux commands.
This page lists 100 of the most used keyboard shortcuts in Linux.
This video provides a tutorial on the keyboard shortcuts for Linux Bash terminal.
To become a Linux power user, you must also know how to set up Linux environment variables in addition to knowing as many keyboard shortcuts as possible. Properly setting up these environment variables can facilitate many tasks in Linux, including configuring the look and feel of the shell, creating environment variables as needed by programs, setting the search path, setting the commands that you want to run whenever you log in or out, and so on.
To learn more about how to set up environment variables in the Linux Bash terminal, read through either of the following tutorials:
You need to know two things when you use a Linux command that is related to an environment variable, as follows:
- The scale of the impact of the environment variable (e.g., a global environment variable or a session environment variable)
- The Linux system file that the environment variable should be put in (e.g., a global environment variable should be put into an /etc/environment file; a session environment variable should be put into a .bashrc file or a .bash_profile file for a Bash terminal)
Because you have access to a cloud-based Linux terminal, you can practice what you learned from the tutorials above by yourself. Log in to your account at AWS Virtual PC, and try some of these Linux commands.
Answer the following questions:
- In your opinion, which keyboard shortcuts from the tutorials (i.e., the Web pages and short videos) will be most useful? Why?
- You need to set an environment variable to hold a printer that will be used by all of the processes in your terminal. What Linux commands will you need to make this happen?
