How do files appear in the directory, are they copied or moved/renamed.

If copied, then how are you going to avoid copying a half copied file?

Somethine like this?

find . -type f -newer afterme.txt | cpio -dumv <new directory>
touch -t afterme.txt

Touch the file once manually. Then after you have found the list of files touch it again.

manually:

Code:

touch my_touch_file

Then in the script:

Code:

find <dir> -newer my_touch_file > listoffiles.txt
touch my_touch_file
cpio -pdumv /somewhere/else < listoffiles.txt

or do it in the background:

Code:

find <dir> -newer my_touch_file | cpio -pdumv /somewhere/else &
touch my_touch_file
wait

Save the list fist, and then feed that into cpio, otherwise you could get a file that will arrive while you are doing the cpio and you'll never retrieve it.

Porter has a point which I was also wondering about, how can you be sure you won't get a partial? If it is longer term storage it doesn't matter since you will get them next time around, but if the files are being processed then you could end up processing an incomplete file.

Hi can some one tell me the alternative for
-mmin command?
Its not working in SunOS

-mmin -30 means 30 or less minutes.
Use touch to set an mtime on a dummy file - the mtime being 30 minutes ago.

Code:

touch -t 200903170800 dummy
find . -type f -newer dummy
