    The kernel as such only manages hardware and does supervisory tasks like scheduling, memory management and starting and stopping processes. There are plenty of DOS-like commands in Linux but they are handled by a different program: the shell. Actually that's true of DOS as well: it has a kernel called io.sys and a command processor called command.com. The two work together to give you the DOS experience.

    In Linux, you have a choice of shells and even the most primitive (the Bourne shell) is far, far more powerful than command.com! The default shell is a derivative of Bourne called bash and it's quite rewarding to learn to use it. It's often much faster and more efficient than using a graphical interface. If you like working at a command line, you'll love Linux.

    Thanks Hazel! Like command.com for DOS which gives you "internal" commands, how do I find out about the shell "internal" commands?....

    Here's a good place to learn about the shell and command line in Linux:

    LinuxCommand.org: Learn the Linux command line. Write shell scripts.
