Goal
Learn basic Linux commands and set up your system for the
semester.
Overview
With Linux, you can use either a graphical user interface (GUI) or
enter textual commands (command-line computing). When you
login to a USF computer science computer, you'll see the Linux GUI.
You can get to the command-line by clicking on the red hat in the
left lower corner, then choosing System Tools and Terminal. The
terminal window that appears will allow you to enter commands
Referring to Directories
Where as Windows File Manager has a root named 'C:', Linux has a
root directory named '/'. All other directories are in a hierarchy
below that.
With your CS account, your home directory is:/home/yourUserName
Professor Wolber's is /home/wolber
You also have a web directory: /home/web/yourUserName.
Linux Commands
Login to Linux, open a terminal window, and try the following
commands.
ls

Using Linux on USF CS Machines

Goal

Learn basic Linux commands and set up your system for the semester.

Overview

With Linux, you can use either a graphical user interface (GUI) or enter textual commands (command-line computing). When you login to a USF computer science computer, you'll see the Linux GUI. You can get to the command-line by clicking on the red hat in the left lower corner, then choosing System Tools and Terminal. The terminal window that appears will allow you to enter commands

Referring to Directories

Where as Windows File Manager has a root named 'C:', Linux has a root directory named '/'. All other directories are in a hierarchy below that. With your CS account, your home directory is:/home/yourUserName Professor Wolber's is /home/wolber You also have a web directory: /home/web/yourUserName.

Linux Commands

Login to Linux, open a terminal window, and try the following commands. ls lists the files in your current directory. pwd tells you where you currently are in the file system. mkdir programs creates a new subdirectory called 'programs' cd programs

changes you from the current directory to the subdirectory 'programs' (if it exists). After running this command, try pwd again. cd changes you from wherever you are to your home directory. Try pwd again to verify you are back in your home directory. cd .. takes you up in the directory hierarchy, e.g., if you're in /home/wolber/programs, it will take you to /home/wolber. passwd changes your password. Do this. Here's some more commands. You'll need them for the tasks set out below, but don't try them right now. cp src dest copies a file named src to a file named dest. mv src dest moves a file from src to dest rm file removes a file (be careful) rmdir directory removes a directory

Task: Modify your programs directory

Use commands above so that you have the following sub- directories: java python Under each, create a subdirectory for 1) samples, and 2) projects. ‘samples’ is where you'll put programs you do in class that perform specific operations. ‘projects’ is where you'll put the larger projects you complete. After creating these sub-directories, perform an ‘ls’ to list them.
