Command Line
From Fmepedia
Command Line refers to the old-style MS-DOS command line, which in turn borrowed a lot from Unix shells. Rather than a mouse-driven GUI, the command line interface (CLI) depends on the typing of commands on the keyboard. As it is often easier to enter a number of parameters that way and to batch commands, the CLI still enjoys some popularity today.
On a normal Windows system, the command line can be accessed through the Start menu, or by opening the run window (windows-key, r) and typing 'cmd'. The Windows command line is somewhat limited in options, though enough to start FME. For a more complete experience, try Take Command by JPSoft (http://jpsoft.com/)
