Usually the compilation is done using the "make" command if the developer hasn't created a .sh file that includes the "make" inside of it.
And most of the times "make install" is the command you can see for installing the compiled program on the system. This could differ from program to program, developer to developer, language to language.
However, if you get a Makefile, it definitely uses the "make" command and if you use "cat Makefile" you may be able to get an idea on how to use "make" commands for compilation and installation.
After installation, the program could be run just by typing the program name on the terminal.

What is the command to switch between the CUI mode to GUI mode and vice versa?
A GUI is typically not operated using text commands, so your question makes little sense. To start the "GUI" on most Unix and Linux systems, you need to launch the X server. Most systems include a simple script, "startx", that will do everything automatically for you. You can also launch the name of the display manager, such as KDM or GDM, manually. When you start the GUI, you are, of course, expected to actually use a GUI, not the command line. Most interfaces will provide some sort of button or link for you to click and shut down the system or exit to the command prompt.
What is the most graceful way to get to run level single user mode?

What command can be used to start a program with a lower scheduling priority?
Use the nice command.
For some reason i do not know, "niceness" is measured backwards from -20 (very high), to 19 (very low).
To use it just do:
/bin/nice -n
This is for LINUX systems only, I think. I am not responsible for what it might or might not do on Windows, Mac OS X or anything else!
