date-specific cp/mv

Hi group,

I'd like to be able to cp or mv certain files from a
dir according to their timestamp.

man cp mentions the '--preserve' option but I don't
think that's what I need.

Does somebody know of some sort of script or perl or
python pass that'll do it?

-Maxim

Have a look at find. You can whip up a one-liner using the
-atime, -mtime  
or -ctime tests (depending on your intent) and use -exec to
do the cp or 
mv...

something akin to:

find <srcdir> -type f -mmin 5 -exec cp {}
<destdir> ;

will copy all files in srcdir that have been modified within
5 minutes
to destdir.  check the find man page for other ways of
checking the
files or restricting how far find will recurse, etc..

I used to use this for moving old mail to an archive folder.
Just change the directories, and you should be golden.
alias archive='find ~/.maildir/inbox/cur -mtime +30 -exec mv
{} ~/.maildir/inbox/archive/cur/. ;'

use find with the time-related options and -exec. To move 
everything in ~/mystuff that's older than 3 days (72 hours)
to 
~/backup, you could use

find ~/mystuff -type f -mtime 72 -exec mv {} ~/backup ;

find has many options related to searching by time (hours, 
minutes, etc) and you can select by atime, ctime or mtime.
It's 
all in the man page

I can't get it to work. I used -ctime, -mtime, -mmin.
The files were created on the 26th of this month using
abcde. All the other files in the dir are at least two
weeks old, so I gave it 72(hours) then 3(days) to grab
everything in the last three days then 96 and 4 just
to make sure. I gave it mmin with 4810(72*60 minutes)
and 5760(90*60). Every time nothing happens; nothing
is copied and no error message is generated. I gave it
relative dirs and absolute dirs. I used -type f and
-fstype <file-type>. Nothing.

I believe the right syntax is:

find /path/dir -type f -ctime -3

This should mean "show all files created for the last 3
days".

Use  "-3" not "3"
