I couldn't find anything about what is setting $SHELL.

In a cygwin rxvt window:

greg AT 7106 ~
$ grep BASH /etc/profile /etc/bash* ~/.bash* ~/.profile
grep: /home/greg/.profile: No such file or directory

greg AT 7106 ~
$ grep SHELL /etc/profile /etc/bash* ~/.bash* ~/.profile
grep: /home/greg/.profile: No such file or directory

greg AT 7106 ~
$ echo $SHELL
/bin/bash

greg AT 7106 ~
$ echo $BASH
/bin/bash

In a DOS shell:

C:\cygwin\home\greg>echo %SHELL%
ECHO is on

C:\cygwin\home\greg>bash
BASH-2.05b$ rm .bash_history
BASH-2.05b$ grep SHELL /etc/profile /etc/bash* ~/.bash* ~/.profile
grep: /home/greg/.bash*: No such file or directory
grep: /home/greg/.profile: No such file or directory
BASH-2.05b$ echo $SHELL
/bin/bash
BASH-2.05b$ echo $BASH
/usr/bin/BASH
BASH-2.05b$

man bash says it sets BASH, but there is nothing about SHELL. Though I
notice on a Linux server, SHELL is also set.

Where is it being set?
