I have installed SUSE Linux with my windows XP.
It came with six GB of software that works well using the icons just like windows.
To run programs from a terminal window you must type the program name and linux command.
The commands I have printed out but wish I had a list of all the program names with a brief discription.
Unfortunately I know of no such comprehensive list. But if you are looking for a program that does something, apropos is a useful command to find it:
$ apropos word
This will return entries for every manual page that contains that word. You can then do:
$ man item
For clarity, I made the command prompt green and what you typed blue. '$' is the standard bourne shell non-root command prompt although you can change it to anything you like by setting the environmental variable $PS1.
You can do an 'ls' on various execution directories, /bin /usr/bin /sbin /usr/sbin /usr/local/bin /usr/local/sbin and whereever else you might have executables and then use the 'man' command to find out how to invoke them and what they do.
