command interpreter
A program which reads textual commands from
the user or from a file and executes them. Some commands may
be executed directly within the interpreter itself
(e.g. setting variables or control constructs), others may
cause it to load and execute other files.
{Unix}'s command interpreters are known as {shell}s.
When an {IBM PC} is {boot}ed {BIOS} loads and runs the
{MS-DOS} command interpreter into memory from file COMMAND.COM
found on a {floppy disk} or {hard disk} drive. The commands
that COMMAND.COM recognizes (e.g. COPY, DIR, PRN) are called
internal commands, in contrast to external commands which are
executable files.
