I need help writing a bash script for the windows cygwin environment. I'm not sure if bash is the optimal tool. Perhaps perl would be better? Either would work.

I have directories whose names include the date they were created. The directory names are in the format of "//remote/builds/SA/Build_YYYYMMDD". I need to
(1) find the directory with the latest date encoded in in it. (all the candidate directories share the same containing directory). Today, for example, I see a directory name of //remote/builds/SA/Build_20060916. Apparently someone preformed a build on Saturday.
(2) Create a directory with the name /cygdrive/c/SA20060916 if it does not already exist.
(3) Find the zip file in //remote/builds/SA/Build_20060916 that contains 'EVAL' in the file name and unzip it to /cygdrive/c/SA20060916
(4) Find the zip file in //remote/builds/SA/Build_20060916 that contains 'FS' in the file name and unzip it to /cygdrive/c/SA20060916

Thanks,
Siegfried
