Use the command below to find files from specific date range

#find . -type f -newermt "2012-11-01" ! -newermt "2012-11-30"

Output:

./testfile.txt
./testfile2.txt

We can use the command to zip all the files we found, here we added a -printf command to just print out the exact file name only without “./” symbol

#gzip $(find . -type f -printf "%f\n" -newermt "2012-11-01" ! -newermt "2012-11-30")
