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.

easier. For example, instead of 'ls' try 'dir'.
'dir' gives more information, and automatically shows
you the listing one page at a time.

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.

.login file (as you might do on other Unix-like operating systems), the
best way to manage your preferences on Galileo is through the
