Cygwin - finding out what package to install

http://www.trueblade.com/knowledge/finding-which-cygwin-package-contains-a-particular-file

Cygwin's cygcheck utility for finding out package needed:

cygcheck -p strings.exe

This will tell you that strings.exe is in binutils. If you know that it's an executable you're looking for, it's best to add the ".exe" extension. If you look for just "strings", you get a list of 144 packages that contain a file with the word "strings" in the filename.
