Check for presence of SHELL environment variable | |
- POSIX states the SHELL environment variable "... shall represent a | |
pathname of the user's preferred command language interpreter." As | |
such, st should check for its presence when deciding what shell to | |
use; just as HOME can be defined to override one's passwd-defined home | |
directory, a user should also be able to override their passwd-defined | |
shell using the SHELL environment variable. | |
