By default, the Shell tool runs the UNIX command shell known as 
bash
. If you would rather use a different shell (such as 
csh
, 
tcsh
, 
ksh
, etc.), or if you do not have 
bash
 available on your UNIX system, then change the value of the variable 
editor:*shell-shell*
, which has the value 
nil
 by default. This means that the Shell tool will use the value of the variable 
ESHELL
 or 
SHELL
 if set, or one of "/bin/sh" (system V) and "/bin/csh" (otherwise).
