Can anyone tell me how to copy files from a directory that have been changed either on a specific date or preferably between two dates and times.

I want to be able to backup all of the files that change within a particular directory on an hourly basis. If I could somehow specify copy every file changed from 9/22/2003 09:00:00 to 9/22/2003 10:00:00 that would be great. If that is not possible, the ability to just copy every file that was changed or created on 9/22/2003 would suffice.

I have checked the documentation on the CP command, but it doesn't appear to have any kind of date range parameter.

Thanks for any help.

become friends with find. Something like:
find /home/larry -atime 7 -exec cp {} /var/backup \;

should get you started. That grabs files from /home/larry that are less than 7 days old and copies them to /var/backup

get more clever with:
find /home/larry -atime 17 ! -atime 7 cp {} /var/backup \;

to get files between 1 and 2 weeks old...

Many thanks Larry.

find is your 'friendly' linux tool to use.

An example: List files in current dir that are
1) older then 3 days [-mtime +3]
2) younger then 7 days [-mtime -7]
3) only in current dir [-maxdepth 1]
4) only regular files [-type f]
5) show hits in long ls format [-exec ls -l {} \;]

find . -mtime +3 -mtime -7 -maxdepth 1 -type f -exec ls -l {} \;

Guess you can work out a solution with this info.

See man find for more great options (-mtime uses days, -mmin does the same thing with minutes).
