>The shell is a command interpreter. More than just the
      insulating layer between the operating system kernel and the user,
      it's also a fairly powerful programming language.  A shell program,
      called a <I
CLASS="FIRSTTERM"
>script</I
>, is an easy-to-use tool for
      building applications by <SPAN
CLASS="QUOTE"
>"gluing"</SPAN
> together system
      calls, tools, utilities, and compiled binaries.  Virtually the
      entire repertoire of UNIX commands, utilities, and tools is
      available for invocation by a shell script.  If that were
      not enough, internal shell commands, such as testing and loop
      constructs, give additional power and flexibility to scripts.
      Shell scripts lend themselves exceptionally well to administrative
      system tasks and other routine repetitive jobs not requiring the
      bells and whistles of a full-blown tightly structured programming
      language.</P
