What Linux Distro and Version am I using????

In the old days, you could just use the "help" menu item to figure this out (drilling down to "about") but now there is so much "helpful" crap in the dialog that opens when you do so, that it has become much less helpful.

So just open a command line and cause the contents of the files that contain your release information to be fed to standard output.

i.e., type:

cat /etc/*-release

More like this

Hey, cool. I think it's more for a program to learn about the system it's installed on, though. I don't really find myself in front of random Linux systems too often. But this definitely goes in the toolbox alongside "uname -a".

There's a better way, command lsb_release which should be in any LSB-compatible (LSB stands for Linux Standards Base) distribution.

Particularly useful is "lsb_release -a" command:

cyberax@lw1:~/work/app$ lsb_release -a
LSB Version: core-2.0-amd64:core-2.0-noarch:core-3.0-amd64:core-3.0-noarch:core-3.1-amd64:core-3.1-noarch:core-3.2-amd64:core-3.2-noarch:core-4.0-amd64:core-4.0-noarch:cxx-3.0-amd64:cxx-3.0-noarch:cxx-3.1-amd64:cxx-3.1-noarch:cxx-3.2-amd64:cxx-3.2-noarch:cxx-4.0-amd64:cxx-4.0-noarch:desktop-3.1-amd64:desktop-3.1-noarch:desktop-3.2-amd64:desktop-3.2-noarch:desktop-4.0-amd64:desktop-4.0-noarch:graphics-2.0-amd64:graphics-2.0-noarch:graphics-3.0-amd64:graphics-3.0-noarch:graphics-3.1-amd64:graphics-3.1-noarch:graphics-3.2-amd64:graphics-3.2-noarch:graphics-4.0-amd64:graphics-4.0-noarch:qt4-3.1-amd64:qt4-3.1-noarch

cat /etc/*-release

does not work with Debian lenny

the file is /etc/debian_version

In Ubuntu, you can also go to System->About Ubuntu. This will bring up a help page with the current version of your operating system, its release date, how long the current version will be supported, a description of the Ubuntu project, and some helpful links.

Try installing acpi.

sudo apt-get install acpi

When you run it, you'll get

# acpi -V

Battery 0: Full, 100%
Battery 0: design capacity 4752 mAh, last full capacity 4752 mAh = 100%
AC Adapter 0: on-line
Thermal 0: ok, 55.0 degrees C
Cooling 0: LCD 0 of 10
Cooling 1: Processor 0 of 10
Cooling 2: Processor 0 of 10

This is very useful if your machine runs hot on occasion.

There is a feature that Apple used to have on the Classic MacOS (I don't know if it exists on OS X, though there seems to be something of the sort still in there) called the Gestalt Manager that would allow you to inquire about the computer environment. It was extremely useful for certain purposes, so much so that Apple actually included it in the standard libraries for Mac development so it would be available on System 6. It would be nice if Linux had something like that, but I don't think the development model is conducive to it, and in any case I don't know how Gestalt handled shared libraries after Apple started using them all over the place.
