[Unix] File management

Yes, I know - it's neither Baking nor DBA. But still relevant.

I had a set of files named .Z.aa that I needed to decompress. GUNZIP doesn't like those extensions, so it ignores it. Here's a basic hack using Cygwin. (You are using Cygwin, right?)

for i in *.Z.aa;
do
    j=`basename $i .aa`;
   echo mv $i $j;
    mv $i $j;
   echo gunzip $j;
    gunzip $j;
done
