How to find out the current cygwin version?

How to find out the current cygwin version?

[Ben Stover via cygwin]

Assume I get to another (Windows) computer where Cygwin is already installed.

How can I find out which version of Cygwin is currently installed?

Or `uname -a'.

This isn't technically correct, right? This gives the version of
cygcheck itself, not the cygwin DLL, which is what was really
being requested.

Instead, use: cygcheck -c cygwin

Or, as I do (and Corinna already suggested): uname -a
or, more quietly: uname -r

Fwiw, from what I've seen, only 
cygcheck -c cygwin 
gives the full x.y.z-n version.
All other suggestions give only
x.y.z without -n

Small difference, but...

To do a check of all installed packages, the second option is really the
only choice.  But if you're just looking for version of the Cygwin DLL,
"uname -r" is an alternative to the first option that is a bit more
UNIXy/Linuxy.  As such, it may be preferable if you're checking this in a
script that is meant to be cross-platform.
