Below are some basics on using Ruby, a SILS Linux server. Your account on Ruby is not the same as your account on the Windows network. For more information on Linux, search on [ https://help.unc.edu ] help.unc.edu.

How do I...

  Changing your password

When you initially receive your Ruby account you will receive an account password from the SILS Lab.

To change your password follow these steps:

  Changing directories

You can change directories by typing the following command at the prompt:

cd directory/subdirectory

If you want to move one directory up in a directory tree type:

cd ..

  Starting a talk session

To start a talk session with someone at another computer you need to know their e-mail address. Then you can type the command:

talk xxxx@xxx.xxx.xxx

When the person responds, your screen will split into a top and bottom. Just begin typing! To quit hit Esc and then q to quit. If that doesn't work, try Ctrl-c.

  FTP'ing files to or from Ruby

See the instructions on [ http://sils.unc.edu/itrc/its/faq.php?id=4629 ] this page to learn how to FTP files on Unix, a PC, or a Mac.

  Printing a file from Ruby

To see a list of available printers on Ruby, type:

lpsat -p

To print either a .ps or a .txt file from Ruby, type:

lp -d printername filename

That is, type lp -d , followed by the name of the printer you want to use, then the name of the file on Ruby you want to print. This only works for .ps or .txt files. Hit Enter to send the job to the printer. You will get an ID number for the print job. Write this down, because if the print job hangs up, you will need this number to cancel the job.

To cancel a print job, type:

cancel ID_#_for_job

That is, type the word cancel followed by a space, followed by the ID number you should have gotten for the job.
