Finding files modified within an hour of another file

Question

If i have 3 files called 1.txt,2.txt and 3.txt for example and they were created an hour apart, say 1pm 2pm and 3pm respectively. What I need is a command that finds all files modified within an hour of a specific file.

I'm in the same directory as the files in the terminal and all files are setuid permission

I've been trying:

find . -type f -perm -4000 -newer 2.txt -mmin -60 -print

This should return 3.txt but it doesn't

What would use to file created in the hour before or after 2.txt?

Answer 1

Try this

touch /tmp/temp -t time1

touch /tmp/ntemp -t time2

find . -newer /tmp/temp -a ! -newer /tmp/ntemp -exec ls -l {} \; 2>/dev/null

where

time1 = time of file creation - 1hr

time2 = time of file creation + 1hr

Ex:

time1 = 201210041500

time2 = 201210041700
