When I don't know or can't remember what variable has the information
I want, printenv is my first stop, e.g.
64> printenv | grep -i cygwin
Cygwin=server
PATH=...
As Brian pointed out, that doesn't find what you need, because it only
lists environment variables, but this does:
64> declare -p | grep -i cygwin
declare -ar BASH_VERSINFO=([0]="4" [1]="4" [2]="12" [3]="3" [4]="release"
[5]="x86_64-unknown-cygwin")
declare -x Cygwin="server"
declare -- MACHTYPE="x86_64-unknown-cygwin"
declare -- OSTYPE="cygwin"
declare -x PATH=...
