PROGRAMMING PROJECT POLICIES AND UNIX INTRO Sal LaMarca CSCI 1302, Fall 2009
Programming Project Policies All programs must compile and run on Odin using Java 1.6.0 (Sun’s JDK) Odin is a Linux server that can be accessed via an SSH connection to odin.cs.uga.edu You may develop your code in an IDE on other operating systems, but it is your job to transfer all files to Odin and to compile, run, and test on Odin using Java 1.6.0 Start projects early and ask for questions as early as possible.
Programming projects requirements 1. All Java source code for the project 2. A Makefile to compile all of your source code 3. A plain text file named readMe.txt that contains detailed instructions on how to compile your source code and how to run your program. The readMe file should also contain a brief description of the files included in the project 4. All Java source code must be commented thoroughly. Each class, function, and significant blocks of code must be well commented.
Getting your Odin account Present your student id to the student workers in Boyd 307, and ask them for your Unix accounts They should give you slips of paper containing login information for your Odin and Atlas accounts I highly recommend changing both your Odin and Atlas passwords to the same password If the student workers in 307 do not have an Odin account for you, please email firstname.lastname@example.org
Boyd 307 open lab The lab includes several Linux machines and Windows machines To login to the Windows machines, use the user id given to you for your Unix accounts, and the password is your 9-digit 810 number To login to the Linux machines, use the user id and password that you use to login to your Odin/Atlas account
Connecting to Odin via SSH Mac, Unix, and Linux users can open up a command prompt and issue the command ssh odin.cs.uga.edu Windows users must download and run an SSH client like putty to connect to Odin http://www.chiark.greenend.org.uk/ ~sgtatham/putty/download.html
File transfer to/from Odin Must use an SFTP (secure file transfer protocol) client to transfer files to and from Odin Filezilla is a free SFTP client that has an easy to use GUI http://filezilla-project.org/
Unix commands (case matters) passwd Changes your password pwd Shows the current working directory man command Get help using the manual page man pwd ls List the contents of a directory ls -la ls -all cd Change directory echo Echo’s a string to standard output
Unix keyboard shortcuts CNTL+Z Stops/suspends the current command fg Restore the last suspended command CNTL+C Kills some commands or processes Tab Autocompletes commands and file names Up and down arrows Scrolls through command history
Unix special command symbols ~ Home directory cd ~ Change to home directory . Currently directory .. Parent directory cd.. Change to parent directory > Redirect output of a command to a file ls -all > directoryContents.txt | Pipes the output of the command to the left to the input of the command to the right ls -all | less
File commands mkdir Create a directory mkdir project1 touch Create a file touch file.txt cp Copies a file cp file1.txt file2.txt rmdir Remove a directory rmdir project1 rm Remove/delete a file rm file.txt mv Moves or renames a file mv file1.txt /usr/file2.txt mv file1.txt file2.txt
Chmod command Changes the permission of a file or directory chmod u+rwx file.txt Permit the file’s owner to read, write, and execute file.txt chmod g-rwx file.txt Remove read, write, and execute permissions from the file’s group chmod o-w file.txt Remove write permissions for other users who are not owners of file.txt chmod a+rw file.txt Permit all users to read and write file.txt
Misc commands cat Lists a file’s contents cat file.txt which Lists the complete path of a command less Scroll through a file quota -v Check how much space you have in your account exit Logs you off ps Shows the current processes you are running kill Kills a process First lookup a process’s id with ps, then issue a kill command like kill 12778 kill -9 12778 You must issue kill commands to stop processes that are taking up a lot of resources (like an infinite loop) Failure to stop an out of control processes may result in having your account frozen or suspended by system administrators
