[SOLVED] Need to find files modified between 15 and 5 minutes ago

I'm trying to find all files in a given folder that were modified withing a certain time frame, say between 5 and 15 minutes ago.

Currently I can find anything modified say up to 15 minutes ago by using find -cmin

#!/bin/bash

minutes="15"

FILETYPES=`find . *PATTERN*.txt* -maxdepth 0 -type f -cmin -$minutes`

How do I give it a time frame?

Try this :

find . -name '*pattern.txt' -maxdepth 1 -type f \( -mmin -15 -a -mmin +5 \)

the parenthesis are not mandatory here with and : -a, but it's necessary for case with or: -o
always use single quotes around the pattern to prevent shell expansion of the wildcard
to give a pattern, use -name or -iname
for the date/hour, -mmin is the way to go for minutes and -mtime for days.
