Re: How to remove those previously downloaded packges?

[LiuYan åç <lovetide at 21cn dot com>]

I've write a script when Cygwin 1.7 is in beta phase, please see this mail on
old.nabble.com
http://old.nabble.com/Cygwin-setup.exe%3A-Clean-historical-setup-packages-ts26569064.html

Here's the updated version for Cygwin-1.7 and Cygwin-Legacy(1.5):
http://old.nabble.com/file/p28443671/cleanOldPackages_UTF8.sh
cleanOldPackages_UTF8.sh 

It simply find setup.ini and setup-legacy.ini in sub-directories (mirror
directories) recursively, and strip out the file list from
setup.ini/setup-legacy.ini, and then find out local files which are not
existed in the file list, then delete it.

$ ./cleanOldPackages_UTF8.sh

Wish it can help you.
