[Solved] CECS326 Homework 0

Purpose: To test your accounts, logins, remote access, demos, and write simple programs on Linux. This assignment is ungraded but should help familiarize you with the Linux environment.

Applications/Utilities directory.

The terminal will start you out in your home directory. It is in /home and is named after your student id. If you do an ls you should see sub directories like Downloads and Desktop.

• Use cd Desktop to go to your desktop. Now, make a new directory called testdir using the command mkdir testdir. You should see this directory appear on your desktop.
• Create an empty file with the touch command. touch emptyfile. Youll see an emtpy file on your desktop. You can open and edit it if you wish.
• Delete the empty file with rm emptyfile. You should see it dissapear. Delete the directory using rm -r testdir. (the -r argument is needed for directories. It stands for recursive.)
• Use cd .. to go back up one level to the root of your home directory. Make a new directory there called Homework00 (this should not be on your desktop, although you can open a file explorer and see it in a window).
• Create 3 files in this Homework00 directory.

1. The first should be called whereami and should contain a single line with the output of the pwdcommand.
2. The second is a python helloworld.py. You should already know how to do this, but perhaps youhavent done this outside of an IDE like pycharm. Id like you to write this with a basic text editor and run it on the command line using python helloworld.py.
3. Lastly, youll write an equivalent C++ helloworld.cpp program in a basic text editor. To compile the program: g++ helloworld.cpp -o helloworld

• After the first homework, work will be done on a remote server called linux1.cecs.csulb.edu. First, run

the hostname command on your local machine and note the name. Then use ssh [email protected] and run the hostname command there.

• OPTIONAL: If you have a laptop or are at home, you may still access linux1 remotely. If you use Linux or a Mac, open a terminal, use ssh -p 2022 [email protected]. If you are using windows, download a tool called Putty and use ssh (port 2022) with that. Note: ssh may work with the default port 22, but this is not guarenteed due to campus firewall rules.
