I need to recursively read through a directory and then zip all the files older than 3 months. All the files have to be zipped seperately.

for file in `find . -ctime +90 -print`
do
gzip $file
done
 

TMOWTDI
find . -type f -ctime +90 -exec gzip {} \;
 

How to zip only unzipped files in a directory.   I have a directory in which there are both zipped and unzipped files. I want to pick up only unzipped files and then zip them.
Something like
if [ file is unzipped ]
then
gzip filename
fi.

Just zip all the files in that directory, those file already ziped nothing happen, those file not zip will zip up now.
cd /directory
gzip -9 *
