File extensions usually don't mean anything in *nix, although you still see them. Mostly as a guide to the user. Executable files generally have no extension so foo.exe in windows is just foo in linux. Text files sometimes have .txt as an extension, sometimes have something describing what they do, like foo.properties, or none at all, like README.
To find out what a file is, it is just examined. On the commandline the file command will give you a best guess as to what the file type is. A gui, like konqueror or whatever gnome's file manager is called, will check for you and display it appropriately. Also, anything executable (whether it's a binary or a script) usually has (and needs) the executable permission set, at least for the owner of the file.
Ronnn:
just follow this guide to the letter works perfectly for java in ubuntu.
http://blog.agileware.net/index.php/arc...0/how-to-install-java-on-ubuntu-linux/
or you could just add a line to your repository list where java is stored although the blackstone is not as uptodate as Suns. once you download the java and install then comment out the extra line in repo list. (if you want the repo address pm me I will have to get it off my other machine.)
or try pclinux os already has java included with it.

If you get a chance and want to play.....PCLINUXOS .92 is a good distro to play with 32 bit.....been using it for awhile....works good so far....another one I have had excellent luck with is Kanotix64 2005-04......just came out....have it installed on my emachine amd64 system....fastest 64bit distro I have ever used....have used kunbuntu and ubuntu....like kanotix better...;and another good distro is Mepis.....love the livecd concept....good way to test your machine to see if everything works.....good luck and have fun.....
In my opinion here are some common commands. help in Linux does show some rather advanced/uncommon commands (most of them) but I'm not sure what all of them do. Here's the ones I use the most.
cp (copy)
mv (move/rename)
rm (remove; delete)
cat (concatenate; one use is for previewing text files to the console)
ls (list folders/files)
dd (disk druid...for doing some advanced disk-related things)
fdisk (quite different from fdisk in DOS but same idea)
cd (change directory)
md (make directory, same as mkdir)
updatedb (updates your file index for searching disk)
locate (locates a file within your file index)
linux32 (only applicable to 64-bit Linux, but basically this runs 32-bit apps)
logout/exit (gets out of shell so you can login as a different user)
su (super user; goes in to root (Administrator) mode)
sudo command (do one operation in super user mode)
file file (look up type of file)
gedit file (desktop only command; edit file with GNOME editor; much better interface than vim)
grep (great tool! use it for finding text from stdin and a pipe; for example: ps -aux | grep artsd will find the arts sound server)
ps (Unix command to list running processes; usually use ps -aux)
top (task manager app that shows CPU and memory)
man (guide/manual for the program you specify)
mount (mount device (disk drive, DVD+RW, thumb drive, etc.) to mount point)
umount (unmount device)
And here's a tip. If you start a program from a desktop mini-console ("Xterm" or "Konsole"), put a space and an ampersand (&) after the program name. That way it won't tie up the console from which you started the program. Even knowing all that I'm pretty much a Linux n00b still, but I can help you with the really basic stuff. I'm pretty good at configuring GNOME/KDE now. Meet GNOME/KDE, your desktop environments. 😉
That's what I was thinking too...
If that happens you probably want to set them all back to read-write (the copied ones on Ubuntu partition). I'm not sure but my best guess is you can probably right-click them all at once just like Windows, properties, go to the permissions tab, and set the read and write attributes again.

Err, that's missing the rather obvious and far more useful man. If you want to know how all the details of how to use a command, type man command (or man man for an intro to that 😉) and it will pop up a page with the complete description, assuming the package maintainer has done the work they're supposed to 🙂
If you know roughly what you want to do, but don't know the exact command, type apropos search term and you'll get a list of suggestions.
