I am using FD in the following situations. 
1.It is a program that is smaller than tcsh, 
  and there is a purpose to use an equal function 
  at the installation and the restoration of system.
2.In the environment of the embeded systems to which the resource is limited,
  it is used with the serial console. 
  (The capacity of RAM is 16Mbyte - 64Mbyte. )
