Some Useful Commands for Galileo

Once you have an account on Galileo, what can you do with it? Here are a few tips to help you get started.
  • Galileo runs Linux, a Unix-like operating system. If you've used other Unix-like operating systems in the past, you'll find that most of the commands you're used to will also work on Galileo. These include 'ls', 'more', 'lpr' and so forth.

    In addition to these standard Unix commands, you'll find many alternate and supplementary commands. These are intended to make the user's life a little easier. For example, instead of 'ls' try 'dir'. 'dir' gives more information, and automatically shows you the listing one page at a time.

    Here are some more:

    Show the contents of a file. The file will be displayed one line at a time. 'type' is smart enough to show you compressed files without having to decompress them first.
    Edit a file, using your preferred editor.
    Send a file to your preferred printer. 'print' will print compressed files without having to decompress them first.
    Invoke your preferred mailer.
    Show information about the system. For example:
    show users -- List the people who are logged on to the cluster.
    show scratch -- Show information about the cluster's scratch space.
    show term -- Show your current terminal settings.
    show queue -- Give information about print and batch queues.
    show cluster -- Show status of each node in the cluster.
    A hypertext-based help system.

    See the section on 'preferences' below for information about setting your preferred printer, editor, et cetera.

  • Rather than setting your preferences by creating a .profile, .cshrc or .login file (as you might do on other Unix-like operating systems), the best way to manage your preferences on Galileo is through the 'preferences' command.
